Materials From Tough-as-Nails Crustacean Could Inspire Better Body Armor

Just to outline what the standard gear can do as of fairly recently; I'm out, but I wore it in 2010.

The kevlar lining in the vest, by itself, is rated to stop 9mm pistol rounds.

The main chest and back ESAPI plates are rated to stop a NATO 7.62x51 round. (The AK commonly fires the lighter 7.62x39 round.)

The armor is bulky as hell. The full assemblage, helmet, shoulder protectors, front and back plates, side plates, etc., is heavy and greatly restricts movement. I found it very difficult, with everything on, to man a gun and drop down to check radios. (I've also never found a decent pair of gloves.) I stopped wearing the neck protection and shoulder protection while driving because I couldn't easily turn my head.

The problem of being trapped is partially addressed through the quick-release mechanism; there is a strap you pull that will simply make your armor fall off. Of course, there's a fairly elaborate system of cables wound throughout the armor, and the armor itself is more annoying to put on.

My feelings are that we're well past the point where the increased likelihood of getting shot while stumbling around is worse than the benefits of not getting hurt by shrapnel. I'm considering a common combined IED and small arms attack in which the convoy is successfully stopped, and they have to kick out dismounts to respond. In that scenario, getting in and out of vehicles is very dangerous (especially some MRAPs where you have to basically go out ass-first) and performing tricky tasks like hooking up tow bars and tow cables.

The next biggest problem is it's hard to allow air flow. The armor tries, and they recently came out (thank god) with a lighter shirt to wear underneath it instead of the regular ACU top. That was a huge improvement, but it's fundamentally hard to put yourself inside a ceramic box and not cook.

Except for shoulders (and no one wants to wear the damned shoulder armor) it doesn't protect joints. The neck protection further restricts mobility.

Wearing it, overall, I felt like a damned turtle. Other people I saw didn't seem to be doing much better.
