The NO-M1-P2900 was developed for use with the NO-M1-1a - Mantus Infantry Power Armor, it became available in YE 29.
A related component of the armor is its propulsion system – the Gravitic drive. By creating a gravity well in the direction it wishes to move the armor can effectively ‘fall’ gracefully and at high speed in that direction. While lacking the brute speed of other drives, it does have high agility as it can stop its momentum in an instant and ‘fall’ in any direction after only a moment simply be redirecting the center of gravity. This allows it to do all forms of highly improbable looking acrobatics in atmosphere.
