well my friend had a pristine helmet and went afk in a tent, don't know why but he did. so after I was done looting I went to hide in a tree and wait for him. sometime I heard 1 shot close like somewhere in the area. i didn't investigate i just waited for him to come back and he said he was bleeding, the helmet went from pristine to ruined, and he was missing some gear. we figured that he was shot in the head, was unconscious to where he could get looted by a player, but was awake when he came back from afk. that helmet saved his life.
