bit boring for the M3 driver though. I guess you could man the .50 and strafe shrubberies to pass the time.
There were specific tanks for this, so if you want an M4 to drag an M3 then the M4 would have a Crane and not a gun.
Why couldn't you just attach a chain from one to the other or a tow rope? Simple. Don't need to lift it with a crane... just have it in tow.
Tanks tow the m3 and the m3 tows my plane to the concrete when i land just short of the runway!!
