The GM-T-1 was built by a deep space asteroid mining group to protect its colonies, assets and peoples against hostile groups during times of war. Built from a salvaged GM Sniper the suit was rebuilt with the intention of making a "gundam killer" capable of taking on and destroying the most advanced mobile suits being deployed by either of the major powers. The rear thruster was removed and replaced with high power two omni jointed thrusters to improve the mechs mobility in space, whilst the chest was extended with two frames covered in armoured panels. The right section holds additional fuel for the thrusters and life support equipment whilst the left holds a searchlight, and a 50mm autocannon with a massive magazine to keep it operational. To assist with pilot safety an additional section of armour was added above the cockpit. The vents and thrusters on the torso were also up armoured and two sensor and EW pods were added either side of the head.
For weaponry the GM-T-1 was fitted with a specially designed railgun. Designed to fire 360mm slugs at near relativistic velocities, the weapon was capable of destroying any Mobile Suit then in service in a single hit, with the velocity of the shots making them effective against even New Type pilots. This came at a cost, as the barrel quickly wore out and needed replacing every 500 shots or so. The weapons integral magazine could hold 9+1 shots and it was unable to reload during engagements. Alongside this the mech carries six one-shot missiles in an ejectable rack on its left arm, made from two scavenged Zaku leg pods.
The GM-T-1 would remain in service with the Deep Mining Republic until UC 108 when it would be shot down over Mars whilst escorting a convoy. The wreck has never been recovered.
