Nice job! Make sure you don't hit him too much, then all the gear he has got on him gets ruined and you cannot use it yourself. When you scroll your mouse wheel on his body, and the 'hide body' option appears, you know he's dead and you can stop hitting him. Normally a headshot by any weapon (without headgear on like a helmet) will kill him.
Just want to share this video with you guys, me and my buddies, a group of five in total, headed to the N/E Airfield to loot and take some names, all the actions you see in this video took place in about 45 minutes...
