Just wait till you progress in the storyline, there are some pretty epic moments ahead for you
I've really loved playing as a Trooper in this game, especially since I'm a Vanguard... I'm right up there, in the enemies faces, stock striking them out and then mortar volleying a group a few metres away.
Of course since you're a Commando, you'd wanna keep things at a distance, but the way the Trooper can be an effective ranged and melee class depending on advanced class is pretty awesome.
Also, I call my ship "Gunsight One" but that's cause I lurve Macross references
