Some years ago I wrote about the then-new Assault Breacher Vehicle developed by the US Marine Corps, which had just gone into action in Afghanistan. Since then the US Army has announced plans to buy several times as many of them as the USMC. Here's a video giving a good idea of how useful it is. I recommend watching it in full-screen mode.
All I can say is, I wish we'd had a few of these things in Angola during the 1970's and 1980's!
(South Africa developed its own version of the mine-clearing line charge, known over there as the 'Plofadder'. [The name is a play on the 'Puff Adder' snake - in Afrikaans, 'Pofadder' - and the word 'explosives' in Afrikaans - 'plofstof'. Putting them together formed 'Plofadder', which implies 'Exploding Adder'.] There were two types, a small backpack unit and a larger vehicle-mounted one. Early production versions were notorious for detonators that didn't fire automatically as intended after the tube had been deployed by rocket. This resulted in some poor sod having to crawl out to it [sometimes under fire], insert new fuses by hand, and detonate them once he'd crawled all the way back to safety. You probably won't be surprised to hear that the job wasn't the most popular in the Army . . .)
