Breach Drill- Old School Style.

SGT Metra talks about returning to core competencies.

The Bangalore Torpedo is simply a tube  filled with high explosives. Its prime use it in breaching wire obstacles. It is over a century old, but still quite effective.

You’ll see the soldier throw a grappling hook onto the wire obstacle. That’s to allow him to yank the line to ensure there aren’t any booby traps (or more technically, anti-tamper devices). The the various sections of Bangalore torpedo are linked and slid under the wire. And then, pull the time fuze, and boom. Part of the delay at the obstacle is for an important safety reason. BTs are only single fuzed, with one well for a blasting cap. But safety demands that they be dual fuzed. A couple decades ago, at Fort Carson, if memory serves, a Bangalore torpedo misfired. The engineer squad waited the appropriate amount of time, and then went forward to diagnose the misfire. And sure enough, it exploded while they were working on it, killing and injuring several soldiers. And so today, in training at least, BTs are dual fuzed- the actual fuze well, generally by a time fuze blasting cap, and a secondary, safety fuzing, by wrapping det cord at the base of a torpedo, and initiating the det cord via an electrical blasting cap. That’s what you see the squad rolling out from the reel.

While competency in the basics of weapons like the BT are important, it should be noted that in general use, the BT has been superseded by the MCLIC and APOBS, which perform the same function, with less exposure to the Engineer soldiers.
