Just over a 140 years ago, Richard Gatling’s famous multiple barrel invention became the scourge of the battlefield with its fearsome firepower and was used by colonising European powers to decimate the warriors of the non-industrialized nations they sought to conquer. Nowadays, the electrically-powered Dillon Aero M134D Minigun is taking the concept to new heights, using six barrels to fire up to 4,000 7.62 MM bullets per minute. As the modular M134D system can be easily adapted to any platform, it is finding favour in a host of new fearsome forms, most notably in the BAE-built Remote Guardian System being tested beneath V-22 Ospreys. Perhaps even scarier is the prospect of the weapon being used aboard the Ripsaw MS-1, a tracked 650-horsepower Unmanned Ground Vehicle (UGV) under development which is capable of accelerating to 50 mph from standstill in around four seconds, turning in its own length and taking a 30 foot high 45 degree hill in its stride. Now is not a good time to be on the wrong team. Proof? Watch this!
