I'm actually familiar with both IED blasts. I served with 4 4 Cav and was deployed with them when both pressure plates were stepped on. The one in this video happened when we had arrived in country and were "RIPPING" with 101 ABN. The ANA soldier that stepped on the pressure plate actually was nick named Commando. Both IED's were in fact 5-liter jugs of ANAL.
The other soldier was Chazray Clark, a fellow Sapper and very good friend. Chaz left behind a wife and young son. He had been home on R&R visiting then just a couple of weeks before it happened.
