You've all probably noted that the M60 has this bipod on it which, in the game, is essentially a usless piecing of thing. I think it'd be really cool if someone made an update to this weapon which would give you an option (in the action menu I guess) to set up the bipod. What would then happen is weapon recoil and inaccuratacy would be reduced and you could only pivot the gun around 25 degrees in any direction.
Edit - Also, I'm not sure if this is an addon or a updated animation, but could someone fix up the stupid M2 machine gun. By fix the machine gun, I'm refering to the way the AI and players man it. The way it is now is ridiculous, the person just sliding around. If the M2 is on the ground and the person wants to adjust aim, they should sidestep. If it's on a jeep, they shouldn't even be able to move their feet all that much and they can't look to the left, right or back or , alternatively, they can't look to the front, left or right.
