At least unlike the fly by wire drones being called state of the art as if fly by wire succeeds remote control-

this one is too obvious other than to be labelled old.

Soon they’ll be breaking out cannons and catapults.

Ever hear of the Rhino Tank? Same deal, probably some Russian grunt in the field, tired of watching his buddies getting killed, figured out what stumped all the headquarter engineers.

“The invention of a hedge-breaching device is generally credited to Curtis G. Culin, a sergeant in the 2nd Armored Division’s 102nd Cavalry Reconnaissance Squadron. However, military historian Max Hastings notes that Culin was inspired by “a Tennessee hillbilly named Roberts”,[6] who during a discussion about how to overcome the bocage, said “Why don’t we get some saw teeth and put them on the front of the tank and cut through these hedges?” Rather than joining in the laughter that greeted this remark, Culin recognized the idea’s potential.[6] A prototype tusk-like assembly was created by welding steel scrap (from destroyed “Czech hedgehogs”) to the front of a tank to create a hedge cutter. The teeth helped prevent the vulnerable underside of the tank from being exposed while it knocked a hole in the hedgerow wall.[11][6] On 14 July, Lieutenant General Omar Bradley inspected the tank[11] and “watched in awe as a hedgerow exploded ... to make way for the Sherman bursting through”.[6] According to Hastings, Culin, “an honest man”, attempted to give credit to Roberts, but this was forgotten in the publicity surrounding the invention. Hastings concludes: “[Culin] became a very American kind of national hero”.
