Also Phil's 250/9 gets a nice buff with the removal of the Open topped rule. Not sure I get that one though...
Still can get fragged by AT weapons, that just means no autokill in assault.
The more important part I think is that it can't get pins from small arms fire.
True, But AT-Rifles, Bazookas, PIATs, Panzerfausts, and Schreks will still put a nice dent in it.
