Captured vehicles

[Imp]

Why not just leave it as is & roll a die to see firstly if you can capture it & secondly if it makes it as far as the next battle without breaking down.
Equipment was often destroyed by abandoning crew, the likes of Tigers the percentage destroyed by the crew rather than enemy fire is high.
Roll a die at the start of each battle for captured armour say a 1 in 3 chance it actually makes it to the battle, just drive it off on the first turn.
That takes care of the cost problem its now a gamble using them plus the crew will never gain much experience in them as they wont be around for long because you cant keep them running.
