I once killed a guy with a rock, I hit him 3 times with the rock, when one of them came after me I executed my grand escape, had a rope ready in the wall in the back. At the end of the round, I noticed I had 1 kill, I played the whole round as collaborator, so...

some time ago in an older version I saw a collaborator squad (6 civis inside), grouping up, picking and attracting lonesome blufor soldiers and stoning them to death.
I was in a blufor squad, we were near the collaborators but had no chance to just spread out and knife them all because of enemy snipers scanning the area. So I was the one who had to go and try to get them, my squad covered me.
When I moved after the civis they run away, i got a bit too far off my squad and stepped into their devilish trap?death by stones. There was nothing my squad could do against them
