I had to take it one time as 3 enemies were running to it aswell.the enemies died and i got the heavy ammo (better me take it and die than have 3 enemies get it etc) A teammate from miles away saw me take the ammo and decided to melee me for a while to say *hey dickhead why didnt you wait*... I then used all my heavy machinegun ammo towards him... happy now... dickhead (op is not the dickhead, just something that happened to me once) I always wait for teammates though
