The machinery is currently fixed in place, so it would mostly be useful in the short term as a way to teach proficiency to recruits and anyone who needs brushing up. In early tests, the developers noticed that people who'd worn MAXFAS were better shots even after taking it off. Eventually, though, there could be a truly mobile version that gives troops a boost in the field. You could one day see armies full of crack shots that aren't easily thrown off by fatigue or the chaos of war.
