OKW Elite Armor Commander ability:
Emergency Repairs is a key piece of technology to which the USF already has access. It allows the crew to repair any critical hits on your tank, at the cost of munitions. Use caution! It leaves the tank crew vulnerable to being killed, and the vehicle to being abandoned. The cost is reasonable, but the use of this perk is only viable in a non-combat situation, in order to quick fix an engine, so that the vehicle can move out of range, in order to undergo full repairs.
Is this still valid? Did some tests and I could not decrew the tanks while ability was in use.
