Armor-Piercing Bullet Turned to Dust When Fired at Composite Metal Foam

Essentially a metal sponge consisting of hollow metal beads within solid metal, composite metal foam (CMF) generally retains some physical properties of its base materials. While its defining characteristic is ultra-high porosity, CMF boasts 5 to 6 times greater strength as well as over 7 times higher energy absorption than previously developed metal foams. Typically created by melting aluminum around hollow metal spheres, it is impressively 70% lighter than sheet metal and 80 times more energy absorbent than steel.

The foam is claimed to be non-toxic, resistant to radiation, fire and heat resistant.

    So,the miracle foam turns the armor-piercing round into dust, eh? Dust that is traveling at 1700fps? In a radius of, oh, .85 inches?
    So the entire kinetic load of the projectile will still proceed through your torso, with some accompanying "metal foam", and you can claim disability for the rest of your life, and vote for Trump, like anyone shot while wearing invincible body armor would? I admit, I am confused, and more than ever of the opinion that when the US sends its merc murderers overseas, they should be executed post operation, so they do not come home and, for instance, massacre a church in Texas. Cheaper than the costs of real psychological care. Just put them down. I mean, for example, just look at Runaway. We, and he, would all be better off.
