Special Forces Unit
Well, I've had an idea for a long time about how to effectively use gas masks and smoke screens and whatnot. Hellsing Episode 5 8:30+ gave me idea for it. What you could do, is launch tear-gas/smoke bombs from, possibly a Milkor_MGL 32 or a EX_41 (Basically a multi-shot M79) or even a standard M203, and then fire into a group of enemies. The smoke screen and/or tear gas would disorient the enemy far beyond their ability to recognize anything or respond, and although this gas wouldn't lethal, the units firing the grenades could fire shots into the gas cloud, or inside the gas cloud, and take out a bunch of disoriented units. Fast, easy, efficient, and if done right doesn't break the Geneva convention.
These units would of course, have to body-suits, and gas-masks and thermal/night-vision/infrared cameras, or have these multiple view scopes on their rifles, which would be expensive of course, but I can see these kinds of people being able to take out large unit structures and effectively reducing the ability of any infantry unit, and even some mechanized units in small numbers. You could send four of these guys out, who'd have a field day ambushing and taking out large groups, with a really high kill to self causality ratio.
I think it would work, but there might be better things, so, I'd like to hear your guys responses and what you think of it, and how I could improve it. blaugh
