Unfortunately he uses lighter armor than the others, which makes him limited, and basically useless for those that need brute force. Cyrus is able to cloak his squad and move in quietly, demolish buildings with explosive charges, and use sniper rifles, making him a very compelling character from a tactical perspective. Cyrus is unique, and most people neglect him, but in the right situations he can often be incredibly powerful, and he's one of the more interesting characters to use. He has four men in his squad, which makes him very powerful, and it also means you'll want to armor him well and build up his defenses. You'll want him to be your tank as he has a talent where he can't die as long as he has energy to maintain his ability.
He can become very powerful and eventually use terminator armor and plasma cannons.
Most people prefer to use him as a medium gunner, since that void needs filling, but the choice is yours. Tarkus is a very well-rounded character that can be built up to suit any purpose.
