The MD-11 was a disruptor rifle used by Lyran Starfleet personnel, especially stormtroopers. It was manufactured by Mizerak-Dorf. Chloe Galarza could barely hit a human-sized target at 10 meters, while Anastasia Volzhin and Carrie Quendelton were unable to hit the broad side of a barn with a MD-11 at point-blank range; yet, the disruptor pistol (and the Type 2A phaser) was even less accurate than the MD-11 was.
