This is a short video of 3rd Marine Logistics Group, 9th Engineer Support Battalion demonstrating how to breach a concrete wall using explosives. They protect themselves with a ballistic blanket, which looks like a scrap of carpet but I'm assuming is not. Would you be the blanket holder? I would trust you to hold the blanket for me. "Awww, you mean that?" God no. I'd rather take my chances with a plastic garbage bag than let you hold the blanket.
Keep going for the video.
Thanks to Grant, who mentioned doing this in marine training and said the feeling was amazing.
