The ASU-57 was designed to be a light-weight assault gun that could be air-dropped out of the An-12 transport plane which was the standard cargo aircraft of the Soviet military at the time and deployed by rocket-assisted parachute

VTOL and Trim for the Main Gun
AG1 for LIghts
AG2 for Parachutes

if you have Cargo planes that can carry heavy things, just try it out ;)
Parachute drop a tank all the way
if it ain't workin' , just keep tryin' add more 'chutes
