COMMUNICATIONS

SYSTEM

Other Options:

●

Insulate/isolate non-essential wiring or cabling with crimp-on end caps, tape, or any

other insulating material.

Secure wires to some structure and tag them for rapid

identification.

●

Any intercom control box can be considered non-essential if one is willing to operate

without it. Disconnect the cable leading to that particular control box at AM-1780 and

consider using field expedient means for intercom.

Also, consider switching control

boxes and/or cables within the vehicle to provide intercom at the desired points. For

repairs of this type, existing cabling can be rerouted if the original cables have been

damaged.

Record the BDAR action taken. When the mission is complete, as soon as practicable,

repair vehicle using standard maintenance procedures.
