Trooper

"'Fix Bayonets.' - The Officer to the Trooper, since the dawn of warfare."The Trooper is the archetypal Soldier. With their reliable skills, Troopers make up not just the base lines of any army but also the Elite Forces. There's nothing quite like seeing a full battalion of Atlasian Military heroes light up an enemy with lasers that outshine the sun.
