Is player armor working by deflecting shots, rather then a flat damage reduction

I'm noticing that when I get shot, especially laying down vs bots, I see a large proportion of shots hitting me, making a sound effect, moving me, screen shake, etc, but not reducing my health. Primarily with weaker hits, think little laser shots.

Given enemy armor is rather complex, with projectile pen, angle, armor rating, armor damage, etc, I figure players may be something similar. It may be a little under tuned, but it may be there.
