So, imagine paintball, on a massive scale.
terrorists versus Army, with unorthodox ambushes going against superior numbers and coordinated tactics.

Then the gear. Each soldier is fitted with a suit of IR receivers, and has an IR emitter bolted to the barrel of his assault rifle.


Yeah, live weapons. no silly training aids here.

The emitters fire a bolt of energy when triggered by the shockwave a blank round produces, so you have to reload, fire, and listen to the gunfire just like a real fight.

Being killed sets off a sonic nightmare next to your ear as your suit starts screaming a high pitched beep. The only way to shut it off is with a special key attached to your rifle. Taking the key out of the rifle shuts it off, but inserting the key in the suit shuts that off, too.
