The Pacifists

After a chance meeting between a fierce warrior and a conscientious objector from opposite sides of a galactic conflict, the two rival spaceship pilots conclude that war is as pointless as arguing with an Orthodox Tautologist. Together they form the Pacifists, a "militant anti-war group" consisting of a perpetual teenager whose species was created in a botched attempt to overcome the aging process; a big rig pilot and former orbital race champion; and a pair of prankster twin brothers.

Of course, battling two galactic armed forces at once is all well and good. It's when you gain the ire of the military industrial complex itself that things really start to go sideways.
