The Mobile Soldier Vajra is an alien organism appearing in a sand-color carapace that is capable of travel through the vacuum of space. This organism has a large tail with a highly efficient bio-gravitational field propeller which grants the creature maneuverability that rivals that of a VF-25 Messiah variable fighter.
Although they don't have wings, they have excellent flight ability in the atmosphere and even when walking upon the ground they can move at high speeds. The Mobile Soldier Vajra is believed to be an intermediate metamorphic stage of Vajra life that can grow to become a Heavy Soldier Vajra. The mobile soldier is the most numerous type of combat Vajra.
