MAST AB-1386/U (NSN 5985-01-381-6341) (EIC:N/A) OPERATOR PMCS WITH ELECTRICAL EQUIPMENT MOUNTING MT-6967/G (NSN MT-6968/G (NSN 5975-01-390-9612) (EIC: N/A)

Total mast height is variable from 8.3 to 33.1 ft (2.5 to 10.1 m) with all mast sections fully deployed. Accessories are provided to assist with guying, anchoring, and operating the mast in its ground mount configuration. They include a hammer, a tripod, guy assemblies, guy stakes, baseplate stakes, crank handle, baseplate, and a radius rope.

Two mounting kits may be used to adapt the HMMWV and the tracked vehicle with brackets and hardware to deploy the mast. The mounting kits are used to anchor the mast to the vehicle and to stabilize the mast when deploying it under normal conditions (i.e., winds below 25 mph [40 kph]).
