I was reading yesterday on this forum an interesting topic about AT guns.
It made me recall a recent battle, where I bought SP guns (not armoured) instead of "normal" guns (it was the first time I tried that). Result : the whole platoon was destroyed in one turn ! A small rifle shot, a pistol bullet shot by an angry crew ... and whhhuf, all goes in flames, vehicule, gun and crew. It seems a bit "excessive".
In my mind, only a shell should be able to destroy the whole vehicule (ie : make it explode). Rifle shots and the like should either immobilize the vehicule and/or kill crew members, as it is the case for the "normal" guns.
That is the same for trucks. Rifle and MG shots should result most of the time in immobilization, not annihilation

Silvarius.
