SUNG LOAOS...


NEW SLING LIMITS FOR CHOPPERS
There's nothing more embarrassing
after lift-off than having one leg of a
sling snap, followed by a second -
third fourth .. ca-runch! !


S" ---"---;==n
That's the theme song of troopers
speeding equipment and supplies into
the fracas. 'Tis mighty sweet music
when those choppers make the scene.
Air delivery means getting there fast-

rigging plus regular sling PM is a
"must" if supplies are going to reach

If you wound up with the short end of the stick when these slings were passed
out, run ) our peepers over Army SC 1600-IL (11 Aug 67) and place your order,
man!
B, doubling the slings you can gain 75 percent of the original rated strength
of those slings, however. "
For c sample, with a leg using a 3-loop sling and a 3-ft sling (ring) add another
sling and ring and you can safely lift 17,500 lbs. You can get the same ratio
increase a ith 2-loop slings. Each 3-ft, 1-3/4-in wide ring, FSN 1670-753-3788,
has a 10,000-lb lifting capacity.

BY DOUBLING THE
SLINGS YOU CAN


BYLCARRYING ATH
GET 75 PERCENT MORE
CARRYING CAPACITY!


HEY,


RIGGING TIPS
Rigging and maintaining your slings
go hand in hand, just like the words and
melody of a hit tune.
For example, nylon webbing rub-
bing against a load generates friction
and heat weakens the fibers ... the
sling can snap just like it had dry rot! !
So, latch onto some scrap canvas and
masking tape.
Wrap the canvas around the sling
where it makes rubbing contact with
the equipment being hauled. Use mask-
ing tape to hold this padding in place.


If you don't
hove canvas,
an old towel
or rag will
do the trick.


Then, for example, when you rote an
MI51 or 500-gal bladder of JP-4 )our
slings won't take it on the chin.

Comes the time when a Chinook picks up supplies the load has to be rigged
and ready to go, with the load weight accurately estimated.
'Course you know the lifting capacity of your workhorse. No doubt your
little green book has a lot of mighty important figures in it like typical load
weights and the weights of various pieces of equipment. Keep it up to date!

JUST RIGHT
Take the 1-1/2 ton, FOR TRANSPORTIN'

weighs 5,615 lbs full.
One 2-loop, 12-ft sling,
Sro 2-loop. I l-ft slings
and one apexing ring r
will handle this baba. p'

That's the kind of info you want at your finger tips because it will clue you
on the sling to use. You also want to pass the weight figure along to the chopper
crew.
Most equipment to be air lifted will have the weight stenciled on it. If not,
there's always the specifications in the TM, right?

When using the A-22 cargo bag, FSN E(K .
1670-242-9169, for hauling ammo, WEIGHS
chow, water cans and such you'll have IN THE

If you use the 10-in, 1-3/4-in wide nylon endless sling, 10,000-lb capacity,
FSN 3940-675-5001 don't use one. Use 'em in pairs to be on the safe side.
When you actually make your hook-up, be sure the link assembly on the ring
is positioned away from the chopper cargo hook... 90 degrees from the hook
is about right.






Once the chopper swings in for the load, brace yourself for
high winds. Goggles and a helmet will come in handy to pro-
tect against flying debris. Keeping the hook-up site policed
up will protect your baby blues and help prevent FOD to
the bird.


If you have the time use a static discharge probe to get rid of the static elec-
tricity. In dry weather it's not much of a problem. Just grab the doughnuts and
insert them in the chopper lifting hook without touching the metal hook and
you won't be seeing stardust!!



OOH
MY ACHING'







CREWCHIEFS CLEAN HOUSE!

The CH-47A has plenty of power so it can lift over the 33,000-lb max gross.
The problem here is that going over the gross weight shortens the life of bird
components and that means more maintenance.
Bird weight plus crew, fuel, tool boxes, armor plate, survival kits, guns,
ammo, rations and troopers with their gear mean your brute could gross 24,000
-maybe 25,000-lbs without an external load.
Try to leave extra gear behind-protect the components!

SAVE THE SUNGS
-When a chopper swings into your
LEIF! pad for a delivery it's going to be on the
LEiP scene only long enough to disconnect
E t,- he load, especially if rounds are "in-
KNIFE! coming."
Still, treat the equipment right so it

Pulling regular preventive maintenance before and after use will keep 'em
in shape.
Say, for example, you have some of those A-7A, A-21 or A-22 cargo bags.
TM 10-1670-238-20 (17 Nov 65) has all the PM services spelled out for you.
The sling gets checked for dirty, worn, cut, frayed or torn webbing and cloth,
loose or broken stitching and for broken, burred or corroded rings and adapters.
Don't use damaged equipment. Get it repaired -pronto.
Strike up the band for troopers who / HE HOW LONG

When nets have been caught in the .. .. rt5 -
rain, spread them out to dry before stor-
ing them. You'll be singing the blues
if you leave them out longer than neces- P/Z/ fA/
sary because direct sun light weakens
fibers.


~CC~L-






Make a simple "A" frame for your slings and hang 'em up to dry out of the
direct sun light. This baby will give you good air circulation and cut down on
mildew which ruins slings.
Hold down on the cleaning bit cause vigorous brushing can weaken the
material. Clean only the soiled areas by shaking and brushing.
When shaking and dry-brushing won't fill the bill, spot-clean cotton compo-
nents by gently brushing or rubbing the soiled areas with a soft-bristle brush or
clean cloth dampened with dry-cleaning solvent, tetrachloroethylene, Spec Fed
O-T-236. FSN 6810-819-1128 will get you a 5-gal pail. Rinse the area with
solvent and let the material air dry.

THE SAME WAY. USE EITHER WITH CLEAN WATER AND
LET IT AIR DRY.
I.Al LGAO GIVE METAL, PLASTIC

WAR TREATMENT.
i /UP

Rough spots, burrs, rust and corrosion on metal and wood that won't clean
off can be removed by using a metal file or by buffing with crocus cloth. Sand-
paper will come in handy on wood items.
If you can't identify the material spilled on the slings, sing out to your sup-
port. You might be dealing with acid, fertilizer or some other destructive stuff
that will mean condemning the sling.
If at all in doubt- don't use the sling. 7 .


S-OTHER PUBS


As you know, some of your cargo bags and other sling-load equipment is
Also used by parachute riggers on air-drop operations. So, if you've got some
time on your hands, rock 'n' roll your way thru these pubs for additional info:
TM 10-500 (7 May 65) Airdrop Supplies and Equipment, General.
TM 10-1670-240-20 (25 Apr 66) Miscellaneous Airdrop Canvas and Webbing.
TM 10-1670-201-25 (3 Dec 65) Maintenance of Parachutes and Other Air-
drop Equipment.
FM 10-8 (22 Oct 64) Air Delivery of Supplies and Equipment in the Field
Army.
Rigging your sling loads does not call for a parachute rigger MOS although
you may get some help from them if you're new in country. Once you get a
little OJT under your belt, tho, you'll be in harmony with the old pros.

Dear Editor,
Ground handling the Cayuse (OH-6A) can tie up 4 men and a heap of time. Like
maybe when the defueling area is some distance from your maintenance tent or shop.
This bump and grind, rut vs gut routine can stir up a mess of maintenance mayhem
for man and machine.
We've cut manpower and time needed for push-pulling the LOH almost in half with
a quack-disconnect attachment added to the towing bar (FSN 1730-967-9556).
With skids resting on stirrups the tail boom rides on a steady keel no dropping
down to sink the stinger; no skin punctures, no mashed mechanics.
Our support welding shop made this rig in jig time. All you need is a couple of
bolts/nuts, 2 quick-disconnect pins, safety wire or clamps, old water hose or rubber
tire, and some scrop iron.
Now 2 men and tug do the.job safer, easier.

EYE THE DIPSTICK
"Easy does it" when filling the hydraulic
brake reservoir on your F-model Seminole.
Pour in MIL-H-5606 to the point of overflow-
ing, and that red stuff will drip down on the
Omni AN/ARN-30D, seep inside the cover and
short out the works. HE
To keep the direction finder set out of the HE FLUID
avionics shop for a thorough cleaning, add NEVER
hydraulic fluid to within 1 inch of the reservoir OVER FIL
top... that'll do the trick.


MOn0 TOW


(Ed Note Looks great. Just tow it slow! 'Specially over rough ground. You
don't want to bend a skid tube by hitting a bump at high speed! This should be
a big help in snow, rain, cold weather.)

KEEP A CLEAN SCREEN
To keep the fuel injector pump And remember the screen gets
of your F model Seminole lubed, cleaned every 3rd PMP according
be sure you eye the fuel-injector oil to the poop in para 5-336 of TM
screen for contamination every 55-1510-201-20 (29 Apr 66).
PMI.
You want clean oil for the oil- FUEL
operated servo which is part of the
fuel injector. A dirty screen will
give you faulty fuel delivery a

PMD COBRA BOGIE WHEELS...


If the fangbird's wheel prangs, it sets down hard and part of the weapons
system-like maybe the XM18 mini-gun-takes a knockout punch in its bread-
basket. Not to mention the possibility of getting a spraddle-legged Cobrabird!
P .- 1, -


A Huey Cobra (AH-1G), the Army's scoot 'n shoot fastback
fling-wing, can be red X'd before it gets a chance to bare its
fangs unless mechanics snub the bogie wheels tight onto the
skids.
First thing you do on THIS BANE
a mission rollout is eyeball FUNNY LOOKING
the landing skid eyebolts. s NEW HAMMER.
Be sure they're not benr, THO
worn or chipped
. 'specially where -
the wheel assembly ;
is attached.


The forward eyebolt is the important one, so check it c-a-r-e-f-u--l-y on your
walk-around. If the wheel assembly doesn't fit snugly against it, the holding pin'll
slip out real easy, too, if you hit a bump while towing the bird.
Next, check the mounting pins on the wheels. Be sure they're straight, not
chipped, cracked, broken. You'll probably find the fixed rear mounting pin in
A-1 condition, but that spring-loaded front pin gets a real Sherlock Holmes exam.
When you add the wheels to the AH-1G, check the space between the pump
cradle assembly and the forward eyebolt. Too much space allows the pin to slip
out 'specially if you're towing over rough terrain.
12


N So-o-o-o, slip a
washer-or t o- E\YEBOLI
on te pin to ill up tde space.
Make sure the wheel assembly -
and e)ebolt are as close as a couple
going steady.
One more tip, Podner. When removing
the wheels, lower both sides at the same
time. Saves a heap of strain on those cross tubes!
True, not every attack helicopter mission calls
for a wheels-on-rollout, but when it does don't FIL UP SPA(E
sandbag your Cobra Cong killer with lousy bogie WITH WASHERS

ENGINE MOUNT HEAT SHIELD
A red hot Continental engine manifold radiates
much heat during takeoff or while full boring thru
the blue. The aft rubber engine mount-about 4
inches to port of the manifold-takes a real beating
from the heat. A simple fix cuts downtime and saves
parts. Could keep your engine from being a dropout.
Adding an asbestos backing to the shield helps a
heap.

*/ USING EXISTING HOLES .
S IN ENGINE MOUNT.

TIRE TIP
That beating the tires get on takeoff, touchdown, roll-out doesn't add up to
long tire life. When you need a replacement, try using a heavy-duty tire. You
can't do better than Cessna's 4-ply with 6-ply rated tire, P/NC-26003-0204, or
one of"these from Army supply system: FSN 2620-542-0127 (6.00x6) or FSN
2620-269-7553 (7.00x6).
Any of these tires will last longer- save you much tire changing downtime
-and they're not so likely to pop on touchdown when a heavy-handed birdman
lands the Mescalero.


WINDOW LATCH, SEAL
Pilots have to lock the window before takeoff, and some heavy-handed types
put too much muscle on the handle. Result: Broken roll pins, P'N NAS561P3-
3, chewed rubber seal, and a window handle that windmills. A cockpit full of
flying debris rakes a pilot's mind off flying for sure.
16






Make a new stainless steel striker
plate to fit over the rubber seal. Spot
weld a 3/8-in wide, 1-in long metal tab
- one end rolled up 1/2 inch to the
striker plate to keep the handle from
turning 360 degrees.
You might want to add a legend to
each window that shows which way the
handle turns: Clockwise for right win-
dow counterclockwise for left win-
dow. Arrow-shaped pressure sensitive
tape with legend written with felt-
tipped pen should do a good job.

Remember .you only have a manufacturer's manual on this Armybird
and these maintenance tid-bits won't show up as MWO's or TB's. Pro-type air-
craft repairmen will dig into their experiences to help them keep the new bird
airborne and mission ready.






The Mescalero is an off-the-shelf job so there won't be any TM 55-series
pubs. Hold on to the manufacturer's pubs and follow them to the letter.
Supply of parts and materials is strictly a local purchase deal with no mili-
tary specs and FSN's assigned.
Take the engine oil, for example.
The oil must meet Continental Motors Corp Spec MHS-24A. At least 9 brands
have oil that meets this spec.

Well, maybe not always-so sticky. Those two strips of
security-lettered pressure tape you may have stuck on the back
of your H-60/PT handset (for your TA-43/PT and TA- S
31'2/PT telephone sets) had a bad habit of getting itself gi SI

It's a good idea to make sure
your PRR-9 receiver control-panel

If this gasket's lost or defective,
moisture seepage could plague the

When you have mike miseries, take off

dirt or mud.
If the element's not clogged but faulty, get
another one put in like it says in para 5-10,
TM 11-5820-549-12 (Oct 66).

Incidentally, be careful not to hold
the antenna so close it touches your hel-

to your head 'cause that grounds 'er too.

what you need is metal-foil decal FSN 7690-877-6865, cover-
ing the CAUTION label, and decal FSN 7690-877-6864,
covering the SECURITY WARNING.
These'll hold better.
The ready-made decals are authorized by TB 750-911-1
(Oct 67) on page 47, but your local command decides whether
you use 'em or not.


In operotin' your PRT-4, have your trans-

the antenna base can be grounded to the

You say you're having capacitors
going kaput in your AN/PRC-47 radio
set when it's tied in with the AN/TRC-
90A, -90B, -129 or -132 radio terminal
set.
Don't sweat it.
You're getting the go-ahead to put
35-35 ufd capacitors (FSN 5910-954-
3038) in place of the CH-474 chassis'
C19-A/B and C20-A/B filter capacitors
(FSN 5910-889-4566). TB 750-911-3
(Apr 68) has the authority for this.
You might also keep an eye out for
this in an addition to TM 11-5820-509-
12P.
The gremlin botchin' up the C19-
A/B and C20-A/B 400 vdc capacitors
is DC surges brought on by variations


in batteries, battery chargers or vehi-
cular generator/regulator systems.
This'll destroy the filter capacitors
which in turn knock the fail-safe saver
off the Q1 and Q2 power oscillator tran-
sistors (FSN 5960-960-7315), and out
they go.
So, to save the day in your portable
Perk, the voltage rating is upped from
400 vdc to 450-525 vdc by the change
in pluck-out capacitors.


WHY SIDETRACK YOUR TRACK?
If you want to get there fastest with the mostest
. .. then take the long way around when you give TM 11-5820-519-12
your AN/TRC-90(), -129(), or -132 radio terminal
set its initial tuning control settings.
That's right. You go the whole route you
follow the book.
No shaky shortcuts like tuning the power ampli-
fier through the receiver frequency. That can burn
out the SHF pre-amplifier tunnel diode amplifier -
which spells factory-repair down time.
Just stick with all the steps it shows in para 125
(a and b), Page 83, TM 11-5820-519-12 (Jun 64), I
and be sure you double-heed the warning about not AN/T -9O
tuning either receiver converter preselector to within
100 mc of the selected transmission frequency. GO BY THE BOOK

) 760-3219


A bent, banged or botched-up antenna connector is like a vehicle with a leaky
gas tank 'cause you can't get much mileage out of either of 'em.
Like, f'rinstance, the J301 connector on your RT-246 or -524 receiver-trans-
mitter when it gets kicked or knocked, leaving it looking like it had been attacked
by a mad alligator.
Your best bet's to protect it with a 3/4-in retainer bushing nut (FSN 5935-
760-3219). You'll find it on Page 6 in Change 5 to TM 11-5820-401-20 (Dec 61).
0' course, you have to make sure the nut's set so the CG-1773/U radio fre-
quency cable assembly's UG-913/U connector clears it.
When putting on this protector-type nut and you find it won't work right,
just ream 'er with a reamer or sharp knife. If this doesn't do the job, get another
nut.

Have you ever wound and set your alarm clock, but were late anyway 'cause
you forgot to test the dinger to see if it was dinging?

If you'd been so casual with your AN/GSS-9 anti-intrusion alarm set you

Ever hear of an M60 machine gun butt stock falling off? It can happen if
you don't put it on right in the first place.
That means lining up the guide grooves in the stock with the receiver
guide rails and then pushing forward until the stock seats itself. And you
know the stock is seated when you hear
a click that tells you the butt stock latch
has gone in the groove on the buffer
assembly cap.
To make sure the stock's locked, give
it a yank or two. Could save you a blush
and bill or three later on. X .i

Spelled out the safety scoop reads like this:


SURE-FIRE AMMO GAGE
Dear Editor, f
We find the best and simplest gage for detecting faulty rounds to keep 'em from
gagging up our M21 subsystem's machine guns is the ammo box tray cover itself.
You have to take it off anyway for loading, so why not put it to use?
The way we do it, one man holds the cover upside down and the other pulls the
linked ammo through. Any round that's too long won't go through. And, if you don't
pull the ammo through too fast, you can easily spot rounds that're too dirty or gritty.

If you jockey one of those new 1-1/4-

They come equipped with a single rifle
bracket mounted on the left side of the
panel behind the driver's seat.
But, on all other trucks, you install

a pair of brackets right up front. The
M151 gets one to the left of the driver
and the other to the right of the passen-

right of the driver.
Anyway, the item you want goes
by the moniker: Kit, Mounting, Rifle
Bracket, and answers to FSN 2590-045-

the M16A1 or the M14, though you
may have to do a little maneuvering to
get the M16 to fit the way you want it.

CUT I1 HER ...
... TO AVOID
THIS BANGING
Nope, your tailpipe's not supposed to tickle your right rear lifting shackle.
If you get a ringing noise when cruisin' along in your M38A1 1/4-ton truck,
that's probably the trouble. The problem's with the muffler there's a batch
of 'em that've got the front flange out o' kilter.
If you've got a ring-a-ding muffler that's in good shape otherwise, you can
rework it so the tailpipe will be turned down away from the lifting shackle.
Just hacksaw the front flange from the muffler pipe. Give the flange piece
about a 30-degree turn counterclockwise. Tack weld it back on. Now hook the
muffler and tailpipe back on the exhaust pipe. If the tailpipe clears the lifting
shackle, finish the welding job.

You can't get a universal-joint parts kit to repair the

truck. You can't if your vehicle comes under Contract

in this series: 4J5353-9998, 4K0001-4199, 4L4424-9999
or 4M0001-4610.
Seems that these trucks have oddball universal joints
on these shafts they have an internal snap-ring to hold
the journal in place. Parts Kit FSN 2520-752-1960 listed
on page 110 of TM 9-2320-209-20P (Jan 65) won't

So ... if you need U-Joint parts--and until a repair
kit comes on the scene ask for the entire prop-shaft,
FSN 2520-752-1013, which is also on page 110 of the
-20P.
The universal-joint parts kit now in the -20P will work

Well, your worries are over, whether your particular vehicle belongs to the
gas or diesel side of the family.
Notes on both page 199 of your TM 9-2300-224-20 (Dec 61) and on page 201
of Cb 2 to your TM 9-2300-224-20/2/1 (Nov 64) tell you to position the bars
on both sides so the arrow on the outboard end of each torsion bar is...

AT THE TOP OF THE BAR AND POINTING
TOWARD THE FRONT Of THE VEHICLE /
WMFN vnnAl CTART S a LJOIWFlFR.


This is the way it should be when you start. However, before you can push
the bar into the torsion bar anchor, the blind splines in the inboard end of the
bar have to be lined up with the blind splines in the torsion bar anchor.
When you move the bar around to line up the splines the arrow may not wind
up at the top and pointing toward the front of the vehicle. When you finally seat
the bar in the torsion bar anchor, the arrow may be in any position around the
circle, (even at the bottom and pointing toward the rear of the vehicle). Mox nix!
There is just one other thing that might foul you up. Page 168 of TM 9-2300-
224-20P/3 PART ONE has the torsion bars for all members of the MI 13/
Ml 13A family except the XM474E2 missile carrier. The bars for it are listed
on page 502 PART FIVE of the same manual. Make sure you order your tor-
sion bars from the right manual and the right part of the manual.

Now you're ready for the sleight of
hand Out of sight up behind the flange
are 3 more wing nuts, and standing
by the filter without ever looking under,
you might never see them.


You can quit squinting at that brass

and like you probably know, the dope
is not in the LO or TM 5-3805-209-15
anyway.
But what could set you up is the
whole new recipe including time-
table.
For that, you watch the clock and the
calendar. The primary filter element
gets cleaned every 125 hours ordinarily,
quarterly at least, and lots oftener in
rough going. Check?
Then the secondary filter element
gets cleaned every 1000 hours, or
changed once a year. Got that?
Sounds simple, but there's a trick or
two you need to know.

THE REST IS EASY
From then on, no sweat, the air hose 6 or 8 inches away, get it
If you found a coat of dust over that good all around, in and out, and then
top filter element, you may be able to turn it over. Blow it off good upside
blow it off with compressed air. Hold down.

,f ament off, give that a good airing our.
too. Then clean out, and wipe out, the
catch tray or bottom cup and the case
that's bolted to the engine air intake.
Make sure you don't leave lint or strings
loose in the case.
IN HEAVY DIRT
If you've been working in heavy dirt and the elements are badly choked,
you may need to wash them out instead of using air.


DON'T BANG IT TO DON'T PUT IT BACK AND WATCH OUT
SHAKE DIRT LOOSE.. TO WORK SOGGY OR... FOR THOSE CONES.

Four wash-out jobs is about all that top element can stand. And if it gets rust
and guck-loaded, change it anyway. Just let nobody ever put oil in that catch
tray, or cup. And no benzine, gasoline, or dry-cleaning solvent on those cores:
who wants a fire on his hands?

Your M2 burner unit, FSN 7310-842-9247, can do a first rate job of cooking ,
whether it's used in the M1937 or the M59 cabinet. But you should always
heed these safety precautions when you're using it.


Take the burner out of the mess hall or tent
when you're going to refuel. Make sure there's
metal-to-metal contact between the nozzle on
the fuel container and the fuel tank to head
off static electricity.


Always be sure the burner is turned off and
cool before you refill the tank. NO SMOKING
means just that when you're filling the fuel
tank. And make sure there's no fuel or other
inflammable material on or near the burner
unit.
Wipe up spilled gasoline pronto. Keep the
fuel tank and fuel container caps tight at all
times. Never store the fuel containers near
heat or open flame.

LIKE THIS..

If the pressure goes into the red area on the
gage when the unit's burning, turn the flame
down about half what it was, and keep an
eye on it. If it stays in the red area, shut the
unit down and let it cool.
Never release any air pressure while the
burner is lighted or while the unit is still hot.


Your generator should operate 450 to 500 hours, depending upon the grades of fuel you use.
When you replace the generator, always inspect the replacement for cracks or any type of
defects. Never bend the tubes or force the generator into position.
When you're operating your burner unit, make sure there's plenty ventilation so you won't be
overcome with carbon monoxide. And, have your fire extinguisher, FSN 4210-270-4512, handy.

With a little care and caution you can master the burner unit... and once you
get the hang of it you won't get the bang of it!

30,45, 60KW GENERATORS...


Second guessing the guys who de-
signed your generator set by disconnect-
ing part of the cooling system never
pays. In the long run it means extra
sweat and elbow grease for you and
your support .. more down time for
maintenance.
Talkin' about the radiator shutter
controls and thermostat, like those on
your Hol-Gar Model CE-301-AC/WK1
generator set.
DON'T
SHUTTER DISCONNECT


It takes a few minutes for a newly-
started engine to warm up to operating
temperatures. Meanwhile, those wide


open shutters feed a rich fuel mixture
into the cylinders and build up excess
carbon on the spark plugs, valves and
pistons.
The same over-rich mixture is fed
to your baby on light loads more
carbon build up.
Before long somebody puts a big
load on your rig and wha hoppen? ?
The engine is so carboned up she can't
handle the load! !
'Course leaving the shutter controls
and thermostat connected means that
the set will put out all the juice you
need. During warm-up and low load
periods the shutters will be partially
closed and you'll get the right fuel-air
mixture. When the engine reaches the
proper operating temperatures,the ther-
mostat will open those shutters as wide
as you please.
If you suspect your baby is running
a little on the hot side, tho, check out
the thermostat.

Gettin' a couple of silent oglers, like
the AN/PPS-5 and AN/MPQ-4A radar
sets, too close together can make a pair
of enemies of 'em. 'Cause when they're
operation' in the same area in the same
frequency band they fight each other's

swearin' at false images. So, keep 'em
apart-say, 50 meters or more. Also,
don't let 'em look at each other.
