I had a look round the forum and couldn't find this ( I'm probably blind!)but what about using another tank to tow the bogged tank out.If the crews' were not under fire then surely they'd stop to help.God knows I've read and seen pics. of daisy chains of vehicles trying to pull some poor dude out of the muck!
Repair vehicles didn't exist maybe ( i don't claim to be an expert....obviously ) but they did have some repair tools on they're vehicles if my eyes do not decieve me,so in a longer battle, while not under fire they may have been able to fix immobilizations ie: damaged treads.
EDIT: I don't mind the bogging % just wish you could tow!!!
