1910's Warfare
Also known as trench warfare 1910's war was brutal. It was also partially "line tactics" with fire and advance you would live in a small holes and take pot shots then advance to the next trench. From artillary barages to enemy infantry charges to plane bombing a trench. Machine guns were also a terrible disadvantage for opposing force. They were long range and could fire many shots in just a few seconds. They were however, horribly inaccurate. Naval combat was ships firing back and forth at each other with massive mounted artillary cannons on the ship. There were machine guns and individual guns for close ship combat and planes though. Artillary was more accurate then from the previous centuries and was capable of vollying sheels massive distances to strong points and enemy advancements. Air combat was innaccurate and scary, plane malfunctions and little or no parachutes made planes horrifying yet important. AA guns could take down planes from a distance but a plane could tare apart an AA with a barrage of bullets. Cavalry was almost gone, but still used for charges all with guns but they were soon replaced by tanks which were immobile but had a few big guns and offered protection from bullets.
