The Mind-Adapted Rail-Employed Weapons System is a top-secret prototype weapons delivery system in which its development was personally supervised by Princess Celestia. Even though projectile weapons were outlawed by Princess Celestia a few years back, the drive to make sure absolutely nothing goes wrong on the SESEV Equestria eventually overcame her hesitation.
The M.A.R.E-WS uses the user's Beta brain waves to aim the head of the weapon, which come in various variants, from a claw to aid in grabbing objects to a highly-accurate pistol (figure A) and a devastating spread gun (figure B). A rapid-fire machine gun variant (figure C) was developed in limited numbers due to its potentially catastrophic nature. It is known that only Admiral Bridge Burner holds the only working protoype.
To ensure that there aren't any unnessecary deaths that may result in any riots from crew afflicted with Space Madness, projectiles fired from the weapon are in fact Cesium pellets aerodynamically designed to maim, rather than kill. That way, security personnel can be trained to aim for the forelimbs in the event of a shipwide riot.
All variants come equipped with an LED flashlight, a holographic HUD projector, and a Diode laser sight.
SCIENTISTS NOTE: **Due to a looming deadline, most M.A.R.E-WS units need to be frequently calibrated. Shouldn't be a problem, considering the amount of engineers onboard the SESEV Equestria. Chances of damage to wearer, wether mental or physical, are uncertain**
