Breaching Training allows all infantry units capable of capturing POWs to also capture most buildings, with stealth units also having to break stealth during the process. Upon successfully doing so, the infantry used for it will be removed from play, and its original owner will gain control of that building. The timer is reset if the unit is pulled away before completion.
Only one infantry unit may capture each building - If multiple attempt to seize the same one, only one of them despawn.
