Starcraft new unit "Tiger Claw"

My idea of a new Terran unit called Tiger Claw. He has three main modes. First, the regular mode which issued with gauss rifle. This is the lightest and most agile mode of Tiger Claw, in this mode, he acts as a squad leader of space marines. Second, the anti-aircraft mode which he equipped with a missile launcher. This is the middle and somewhat cumbersome mode of Tiger Claw, in this mode, he acts as a mobile anti-aircraft torrent of Terran force. Third, the assault mode which he fit with both gauss rifle and missile launcher. This is the heaviest and most powerful mode of Tiger Claw, in this mode, he acts as a close support unit to remove all obstacle before the Terran might.
