Tested both the Lynx and the M320 (all ammo variants) by putting a couple of AI close to eachother and they never penetrate one to kill or injure the one(s) behind. Weapons designed to go through armour and engine blocks etc i think should be able to go through a body. Only tested bodies so far. Might be too weak vs other materials as well.
Guessing its a "config" thing.
Thank you.
