Vehicle recovery

[Imp]

Decided to have a quick look on the web heres a link to Tiger restoration where he says putting tracks on is not easy. Thought link might intrest some of you anyway.

Found a few refs to Tigers & while a simple job like replacing a thrown track seems quicker than modern equipment still not quick 4-12 hours I found.
Modern tanks heres a link both tracks thrown note the time & need for arc welding gear

Or M1A1 one track thrown 15 hours.
Stuck in mud can easily be longer.
Its a lot faster to change a major component, engines gearboxes etc etc take under 15 minutes running gear has lots of moving parts & is not modular.
Possibly something like a BT (Christie design) tank with simple suspension & designed to run off its tracks it may be possible but on the whole Web supports what tankers say its a long job.
