The M2 Amphibious Support Drone is a robotic land and aquatic vehicle designed to move as fast over land and under the sea as possible. It is designed to provide anti-explosive projectile (fuel rod rounds, grenades, rockets, etc.) cover for friendlies and to hold ammunition stockpiles for them behind armor plating. The M2 is equipped with anti-gravity pods powered by the on-board hydrogen that it uses to hover above the ground. Propulsion jets are used to propel the drone rapidly around. Like the M1, the M2 is constructed of a variable-density material that allows the drone to sink or float.
