If I am feeling like a bit of bookkeeping which is not often.
Vehicles which are a total loss have to wait 3 battles before replacing.
I then role a dice to determine what turns up, especially mid war on as Germans.
Can often be something worse or a Stug or TD in place of a tank.

Captured tanks I don't use that often criteria is really up to you but I use mainly as a stopgap.
Usually 2 to 3 battles & I get rid of them, if I capture another similar model I keep the original for longer but don't take the additional captured tank.
Reasoning spare parts & lack of ammo means I cant keep them running.

Halftracks are like gold dust I only have a slim chance of replacing it with anything but a truck, do role every few battles to see if I get a couple of replacements.

Makes you very wary of using them for infantry assault etc as the men would much rather them survive to move supplies etc between battles.
