I apologized to you in teamspeak and told you that I got lost. The sniper team of sheriff had flanked us and killed people next to me. I had to make a move or he would have killed me too. I killed sheriff and had friendlies with me when i did i said lets continue west because i thought the sniper wiped our my team. I didn't hear anymore comms from my squad leader and I was kinda lost at this point and so i continued west which is where i thought the obj was and where i shot at someone with a spotter scope. I didn't realize the friendlies that were with me on sheriffs body didn't follow me. I found the sniper i shot at from a distance and did drag the spotter scope a few feet but i didnt take his gear. It wasn't until i realized where the shots were coming from that i headed back towards the actually obj area which i think brought me to the other side of the compound. I did shoot someone in the back of the head which was friendly and im sorry but based on where i ended up i thought it was hostile. The camo in that mission was impossible to tell apart at a distance so when i found my way back to the obj I held my fire on Gkenny and morlocks group and rejoined friendlies. I'm really sorry and i should have payed attention in the briefing. Ive been here many years without a ban and would like to not mess that up with a big mistake.
