In numerous missions tanks or BMPS have come up to me and not fired on me.. in one case (covert op against house on base) a BMP came up to me when I was prone, and just stopped right up against me so I could crawl underneath. A T72 parked 10-15 feet away by the edge of a forest lookpointing directly at me (it had chased me in there) and did not fire for ages (I sat down, stood up etc) and it didnt fire until I fired a shot at it.
Happened on a custom downloaded mission that all the enemy came up the hill and milled around me, again not firing till I fired a pot shot at them..
Atmosphere killer .. please fix, I used to love this game and its put me off finishing it and playing the exp pack..
many thanks
