"The Verdenna Republic was struck with a hard problem. In a panic, and thanks to miraculous engineering schedule, the T-13 was put together in under a year. A turreted vehicle combined with Ucci's 30mm "mosquito", and a dedicated loader compared to the M1 series, already gave an edg. Combining near impenetrable armor(for the standard M1-33-7, which was the most common vehicle), the T-13 became a bit of a roving bunker, designed specifically to take out these menacing threat. Despite being a threat to all M1s that exist, the T-13 did have a minor problem, primarily concerning the armoring of the turret. Even with a 60 degree angle, the backside could be penetrated, and the sides proved that anything short of 50 degrees would cause a CDC 33-6 to penetrate. This prompted the development of a successor, but 42 T-13s still hit the frontlines, and proved incredibly successful."
