Well of course, the standard light, medium and heavy armor, sub machine guns with high rate of fire, low accuracy and low damage, assault rifles with short to medium range, medium accuracy and medium damage, shotguns with high damage and short range, sniper rifles with long range, high damage and high accuracy. The usual artillery. Then if we will get laser/plasma weapons it will change alot of the above said, plasma is high damage, slow firing whilst laser would be medium damage and have a fast rate of fire, it's all about the imagination :)
