Battle by joystick. Ace quoted this piece on the use of CROWS (Common Remotely Operated Weapons Station) in the Middle East:
The remote control turret changed the battlefield more than you might think. It all began three years ago, when the U.S. Army realized that new remote control gun turret designs actually worked, and suddenly they could not get enough of them... The main issue was that the enemy was no longer able to knock out the turret gunner, early in a firefight, and take away a lot of the vehicles firepower. Because of that, once the enemy opens fire, they are in trouble. The remote turret tends to begin delivering accurate fire right away, and is much more immune to enemy fire than a human gunner. If the vehicle is a Stryker, the enemy will soon find themselves dealing with half a dozen or so heavily armed infantry, who get out of the vehicle and come at the ambushers. Iraqis don't like that. They also don't like how some of the CROWS turret equipped vehicles will come after them. All those accurately aimed bullets coming their way, and no enemy soldiers in sight, is demoralizing.
