Jelly in your armor

Back in high school, I killed time in AP Chemistry one day figuring out what would happen if someone in the Rifts setting wearing typical personal body armor were hit by a typical rail gun burst. The basics:
A Rifts rail gun burst involves multiple high-velocity projectiles
It doesn’t breach the armor (always nice to have body armor that can stop anti-tank weapons)
The outcome, in short, was that the target would be sent flying across the landscape at a remarkably high speed, certainly beating them to a complete pulp inside their amazing armor. It’s a fun, if icky, SF image.
At least the armor’s recoverable.
