Light infantry typically have only their gauntlets for primary offense (beam andpulse shooting) and defense (forcefield projection up to 2ft in diameter, 1ft away from the gauntlet). boots, gauntlets, belts and gauntlets altogether provide forcefield defense just enough to contain atmosphere, repel foreign liquids, dust and gases, and once the wearer is alert, to deflect bullets or cushion against small explosions.
Above that, here, is the equipment of a bell rifle for firing large pulses or mild shield bonus, a floating shoulder cannon for anti-air tactics or demolition, thigh- bands to boost her shields over all exposed skin, and a jet pack for either chasing resilient targets across great distances, or escaping a very large threat.
The shoulder cannon design is a loose draft and still unsure. The jet pack also contains the power core for all the equipment because this wearer is not a maarite and cannot power the things from herself.
The character is a green haired rocket-carrying tomboy OC who belongs to an irl friend. I don't think he has a dA account.
