In a matrix-related vein powered exoskeleton technology is becoming good/cheap. A reasonable way to prevent brain injuries from getting rattled around by an IED is to make yourself REALLY heavy and then power it so you don't get really tired walking around on patrol (i.e. powered armored exoskeleton) Speaking of horrendous there's also those supposedly non-lethal ray guns they are testing on journalists holding mattresses.
