unfortunately i have to disagree with shields, magnetic fields maybe, not shields though, the power needed to survive even 1 shot would be astronomical, and tests done by the americans in 1980's (i'll try to find the article) showed that the feedback caused by the field collapsing basically fried everything electronic and electrical (i'm talking about shields not the forcefield above).
i'd personally go along the lines of dampening fields which lessens the impact of the projectile, and theoretically allows faster vehicles/powered armor/aircraft, and allows personnel to survive the harder knocks, possibly even tank shells on "powered armor" (in the loosest sense, more along the lines of a modified ricas with powerpack) without even staggering.
and shorter term, micro-laser lasers to detonate larger/slower projectiles (RPG's, 120mm, badly made 7.62mm), might even be able to miniaturize them enough to fit the weapon and sensor on shoulders and helmets, maybe even use that telepathic helmet to make it into a hidden weapon for last ditch situations.
