Well I managed to see a infatry man with hand grenades take out a tank (well, imoblized it anyways).
I was playing the demo for CM:BB on the mission were a large force of Russians with two tanks and hundreds of men were attacking a small, strungout bunch of frontline Germans.
The Russians tanks managed to take out my only "true" anti-tank men and was moving through my lines with no infantry support( :confused: ) passed near a small group of normal infantry and one through a a hand grenede and hit it tracks.
After I got over the shock I then relized I had a big, ugly enemy turret in the middle of my lines.....
Thanks for the info guys and I'm reading over the links right now.
