It’s difficult for military strategists to envision new forms of battle when they’re focused on those at hand. Before the advent of flight, military commanders cared only about how to wage combat on land or at sea. It wasn’t until 1915, when the French pilot Roland Garros flew a plane jerry-rigged with a machine gun, that military strategists realised that war could actually be waged from the skies. Then, once aircraft began engaging in attacks, army units on the ground pivoted as well, creating compact, rapid-fire antiaircraft guns. And so the evolution of war continued.
