A subsequent design would be tried again in 1915 due to the lack of armored vehicle options for the French military at the time, something that would be remedied with the Schneider, the first French tank used in 1917. However, once again, the design for the Boirault Machine would prove inadequate, though this time, Boirault did add 45-degree turning functionality, something vacant from the first prototype. The same problems that plagued the first design were still present in its follow-up, as the vehicle moved entirely too slowly and took too many resources to manufacture.
Later, Boirlault would again improve upon the design one last time, adding a more secure steel cabin that could protect the crew from gunfire and had a larger turning radius than previous models. The vehicle still utilized the same concepts as the first model but could be more viable on the battlefield because it actually protected the machine’s operators.
Ultimately, however, none of these improvements were good enough for the invention to be deployed, and the vehicle would be nicknamed “Diplodocus Militarus,” named after a large, sluggish dinosaur. Later, tools like the Bangalore Torpedo, a subterranean explosive that could blow up the barbed wire, would go on to be used to clear the dangerous obstruction during World War 2.
