Which war do you think revolutionised warfare/the world more?
The Civil War introduced automatic weapons (the Gatling gun) which would malfunction a lot, improved ammunition that would increase damage in wounds (the mini-ball), introduced repeating rifles (the Henry, Spencer, and Winchester), and introduced improved accuracy in weapons (the Springfield musket) which included grooved barrels. Not to mention self-contained cartridges (prototype to the modern style bullet with powder already within a cartridge with the projectile facing outwards).
On the navy side, they introduced ironclads which improved defense of ships. They also introduced the prototype to the tank; aka an ironclad with a submarine's body (mostly submerged underwater with the exception of its rotating turret) and a large cylinder which contained a cannon that was protected by more iron and could be rotated near-360 degrees (see: U.S.S. Monitor)
Also, the military telegraph system was then introduced under Lincoln's presidency in a genius way to communicate more efficiently. Plus, they also experimented with their weapons which would pave the way to our weapons today; such as the LeMat revolver which included a standard revolver with an underbarrel shotgun attachment that could fire either simultaneously with the revolver or one at a time.
Not to mention the addition of the railroad system as a warfare tool (only used once during the war at the Battle of Manassas/Battle of Bullrun by the Confederacy). It introduced, however, more ways to deliver supplies and transport for troops. Also, medical care slightly advanced since the Revolutionary War and the Mexican-American War with the help of Clara Barton, an active nurse that either treated soldiers on the front line or after battle. Her methods increased the ways to aid soldiers (see: triage).
World War II fixed the issues with other common automatic weapons and set forth the sub-machine gun and assault rifle (more refined than those present in WWI). World War II also introduced advances in medical care when wounded and increased on the self-contained cartridges introduced in the Civil War. With all of this other stuff happening to then-common warfare, the newest inventions to grace the world were just getting started.
With naval warfare completely blown out of the water by the time of '39, the all-new armoured artillery called tanks that would invent an entirely new tactic called "blitzkrieg," and the brand-spankin'-new air warfare made this war something to see. Up into World War I, in order to fight wars people would perform Napoleonic tactics. AKA, line up and fire. Line up and fire. It slowly evolved into trench warfare introduced in World War I and just said, "Dude, you can get stomped on by rolling metal that can blast your face off, you can get bombed by things flying overhead, and you can be shot from anywhere with this newly-added accuracy in weapons!"
Technically, all of this new stuff made it impossible to hide. Not to mention World War II also introduced new technology including radar, the jet engine, absolutely ridiculously effective bombers, and massive new bombs to go with them. This now brings us to our final point of World War II: the atomic bomb.
The atomic bomb reshaped warfare and caused several other wars to start because of it. It made everyone paranoid (and still does) to the devastating destruction that it performs.
So, forums, which war do you believe revolutionised warfare/the world?
