ERISS: And ability to destroy our own tanks, so they are not captured.
Like the so many just immobilized Abrahams in Irak towns, then destroyed by A10s... What a luxury USA could afford lol.
Even if you cap something you will get nearly 0 training for you caped unit, reasons for it are next
1 Game is one-timeline (at least companies) meaning that you troops won't hawe too much time to learn new machine
2 You limited in human power, ifnantry are infantry, tank crews are tank crews, where you gonna get new troops or are you sure it's ok to put someone in half-destroyed or almost destroyed tank and make them preform extra poorly + in damaged machine ? Just think about it, they can preform a way better if they just get their LAWs/Fags/RPGs and hide till someone gett in efficient range/ sneak close anihilation distance
3 Limited ammo + chanse of damaged munition + if you will try to change canon it will take too much time in compare to game leights + there also stabilization systems, chanse to damage cbn, engine and tons of other things
4 Lack of spare parts/ability to fix them.... because it's their toy and they hawe parts for it....
5 Are you playing agains -100 morale sides lol ?!
