Same thing happened to me tonight kind of .This guy was all over my 6 and somebody was helping to save me. I cant remember who was helping me but he kept saying to me on the on the radio, "I hit him I hit him". But he never went down. Then finally I got 1 little lick in and I got the kill. Makes no sense. Guy helps me out and I get the kill. Not fair. I wanted my countryman to get the kill for helping. And he was bumming real bad all that help he gave me and I got the kill. Dangit.
