Yup, it's called a spade

The cynic in me can't help but think the material isn't going to add any/much extra bullet resistance, it's all coming from the earth inside it. So knocking up a quick foxhole and building up and compacting the earth around it should be just as, if not more effective (because you're defended 360 degrees)
