1.±
Install the MILES tank firing insulator card between the firing contacts on the right side
of the main gun breech ring assembly. Without this card, circuit breaker #19 on the
turret networks box (TNB) or redesigned turret networks box (RTNB) will trip and disable
the firing circuit. Don’t forget to remove the card after the tactical exercise is done.
The insulator card doesn’t have an NSN, so you’ll need to make a substitute if it’s
missing from your MILES kit. Just drill a hole through the edge of a flashlight filter and
tie a string to it. Then, insert the filter between the contacts.
2.±
Connect the MILES trigger cable plug labeled P1 CONTROL CONSOLE J2 to the J2
receptacle on the MILES control console.

labeled P2-TEST 1 to

on the TNB or to the

3-10-1,
Operator’s Manual
for Multiple Integrated Laser
Engagement System (MILES), Simulator
System, Firing, Laser, M82,
is being
updated to make the process clearer.
Until then, follow these instructions
for hookup…
OK! Your MILES is
all hooked up!!
You sure
‘bout that?
My LRUs are
feelin’ kinda
funny!
Crewmen, hook up the cables
for your multiple integrated
laser engagement system
(MILES) the right way.
The
biggest
problem
is
installation
of the MILES
trigger cable.
if it’s
connected
to the
wrong
line
replaceable
unit (LRU) or
test jack,
you get
damage
to the
improved
fire control
electronics
unit (IFCEU),
improved
commander’s
electronics
unit (ICEU),
improved
mission
processor
unit (IMPU),
or other
fire control
components
and systems.
if you don’t,
the system
won’t work
and you
can damage
some pretty
expensive
equipment on
your tank.
