"two received concussions and two others received minor burns."
Yeah, but the lived.
We need a lot more of these in the field, we have discovered something that can withstand many of the IEDs and ballistic projectiles. V bottom to deflect the underneath blast and more armor on the sides to protect against ballistic blast.
However, that said, if the IED is one of the 155mm variety...there is very little, including an Abrams tank, that will be immune. Simply too big and powerful. But the numbers of those are limited as compared to these others and every life saved is absolutely critical.
