Captured vehicles

[Imp]

Are captured tanks so alien to experieced tankers to figure out?
I think not as WW2 tanks were not really very complicated as modern tanks are

With many old vehicles there was a knack to getting the most out of them as not refined like the modern stuff we are used to, some call it character. Could be anything from clunky gearboxes to overstreesing somthing if you dont treat it nice. Modern stuff the problem is probably fiquring out whats what cause its not writen in your language.
In both cases this leads to lack of familiarity & hence delay & or error that could get your killed.
