The suit has :
* physiological and biological sensors
* actuators that serve as the muscles to power the suit
* processors and computers,
* and a durable exoskeleton that offers support to the operator.
* the helmet has thin, transparent glass with ballistic protection and a heads-up display
It will provide protection against shrapnel and small arms fire, but could be targeted by an electromagnetic pulse weapon.
Special force exoskeletons have need to operate under for shorter times than Army exoskeletons would.
Powered knee joints could help armored exoskeleton wearers to climb 100 flights of stairs and then still engage in combat.
A commando might only need to breach a fortification and be involved in a short fight of an hour or less.
An Army soldier could need powered exoskeletons to operate for days between recharging.
