The United Terran Dominion and Royalist Republic continue their centuries long war with no end in sight and resources dwindling. Both sides fight bitterly in a stalemate for any resources they can get their hands on.
Due to a limited pool of candidates, 1st Lieutenant Alexander B. Wellington is sent to the border world of Gallis II as a replacement XO for the 15th Heavy Mechanical Tactics Unit, an infamous vassal combat unit. He won't have an easy transition into the unit. Alexander will have to deal with UTD Battle Mechs, learn that tanks aren't one size fits all, and handle a pair of twins with opposite personalities.
But will the battles Alexander face end with one side being the loser or will he face something far worse that will take a toll on both sides.
