I taped one of the combat offloads I conducted on a local training line out of Charleston AFB, SC. Circa 2002. Basically a combat offload consists of the pilots pushing the engines up to power, standing on the brakes. As the loadmaster you may hear me say (over the noise) 'Standby......Brakes....Release' - at which point the pilot releases the breaks as I simultaneous unlock the pallet locks in the floor holding the cargo from going fore and aft. At that point the cargo flies out the back and I would state 'Load Clear' and then we stop and reset for taxi. It's a long video and alot of it is boring as we back the aircraft up (that's me saying 'Come on back, come on back, etc etc while I am sitting on the back of the ramp).
