As a combat veteran who has dug many sandbags and had his Marines killed by sniper fire while standing behind a machinegun exposed from the chest up, I can promise you that anyone who has ever served would love to have this! Great invention and from the looks of their website (www.ddmat.com)they have tested against large bombs and done well, there's even video! BTW, if you think sandbags do good against bombs or trucks you are wrong! And honestly if the truck got close enough to ram it, then the guy inside wasn't doing his job. Get it into the field ASAP!
