After looking at the prototypes, they concluded that the ballistic plates were the only serviceable ones. The ballistic visor, albeit impressive, was still deemed impractical until further improvement could be made to the hinges that attached the visor to the helmet itself.
Even though it was rigid, the further report from the documents showed that the hinge still tended to break down after being hit from a .308 round. To make it worse, the bullet had the tendency to ricochet from the ballistic visor itself. It was still in its experimental states, after all. As for the radio, it was just a soldier's radio left there.
They replaced the ballistic plates they were currently wearing with the new plates. It felt lighter, and it was a little bit thinner than the boron carbide plates that they usually wore. Still, Del preferred this new plate over the old one, although it had saved him many times from bullets, or at worst, laser.
