The 155th, I believe, was destroyed at least 6 times, including no less than 3 times at Vuhledar, and the last time recently in its Kursk-Sumy offensive (where most of its officers were wiped out due to a HIMARS strike). As for the future, absolutely no idea...
Cant be too much fun being 7th generation of 155th fodder, knowing the average lifespan of a generation is about 5 months. Pure death sentence. My favourite generation was the 2nd - young and promising moscals, rushed in with no training after the originals were wiped. They lasted a few days.
