Great article about bulletproofing efforts at MIT and Rice University. One has to wonder how much such material can lighten up the body armor our folks wear into combat, including the helmet, while increasing ballistic protection. Especially if they can keep the cost below a jillion dollars per Marine.
The material will have to be extensively tested, obviously. This includes the crucial “Lance Corporal Using the Helmet to Hammer in Engineer Stakes” test. But Marines have been begging for a helmet that is ballistic proof against 7.62×39, without excessive weight that makes extended wear a problem.
