Reactive armor's protective mechanism involves producing an explosion or other such reaction when it is impacted by a weapon, actively "pushing back" against it. This is particularly effective against shaped charge warheads, in which the warhead directs a focused jet of molten metal against the armor; reactive armor's reaction disrupts the jet before it reaches the armor's surface.

ERA for G.Is. Wouldn't one failed armor just blow up the person wearing it? And wouldn't the detonation of the ERA to blast the bullet away basically blast you with shrapnel?

Current personal body armor works fine...

Wouldn't the explosion in theory cause the soldier to get knocked off of his feet? So getting knocked down is a problem, especially if the bullet could be stopped by other means.
Then of course, as cited, weight and limited flexibility is a problem.
I figure the only practical idea at this point for reactive armor is the one that works on the corn starch concept. Basically it's liquid in a bag normally, but a high velocity object causes it to harden nearly instantly.
Either way since both ideas are years away, our best bet is probably good old kevlar.

If it was set up for a response to low level pressure, and you fell over, you may end up bouncing around like a beach ball
