Poison "Mustard" Gas, Tanks, Machine Gun(First introduced by the Germans which caused severe casualties), Planes, and Trench Warfare.
Trench warfare was one type, and one which was used more than it had been in any previous war (and maybe since then). Also, things such as gas attacks are classed as well as use of tanks to invade enemy territory and fighter planes.
They weren't as such. No more than the horse was invented to carry a cavalryman: Aircraft were adapted to be used in warfare in much the same way as many other things.
Very Brief Answer: They were used by all sides within their own air forces as war planes, to take out enemy war planes, drop bombs on the enemy, and provide reinforcements and supplies to allies behind enemy lines. From their relatively minor role in World War I, aircraft became one of the dominant forms of military hardware in World War II. They revolutionized both land and naval warfare.
Approximately 10,000 planes were shot down during World War 1. The aerial warfare in this conflict was a new and rapidly developing aspect of combat, with both sides actively engaging in air-to-air combat. This led to a significant number of aircraft losses throughout the war.
to call in fighter planes
Trench warfare was mostly used, and planes were used to locate enemy positions
warfare without planes started in 1807 when the pirates ruled the sea's and when the British King sent an English privateer into the carribean to plunder French and Spanish ships for gold and other things of value.

Aztec religious practices influenced warfare by encouraging the belief that capturing prisoners in battle for sacrifice would please the gods and ensure prosperity for their civilization. This belief system gave the Aztecs a strong motivation to engage in warfare and expand their empire through conquest. Additionally, the Aztec military was often led by high-ranking religious figures, further intertwining religion with their military operations.
Irregular warfare
In WWI planes were used for reconnaissance until someone dropped grenades outside of their canopy. Then towards the end of the war fully tactical bombers were developed to dropped heavier explosives.

Both were NEW, SLOW, and UNRELIABLE. Tanks were used to break thru barbed wired trenches; and planes were originally used for aerial reconnaissance (scouting) and artillery spotting (adjusting fire).
It added mobility in force and was a key element in Germany's Blitzkrieg. It made trench warfare obsolete.
In world war 1 everybody fought a bloody form of warfare that was completely static and involved charging over a cover-less field at the enemy trench with bolt action rifles while the trench was defended with machine guns that killed thousands in seconds at a time called trench warfare. in 1917 the British invented the tank which created a break through in warfare and changed war as we knew it as well as planes and the Germans invented the the sub machine gun in 1918 which allowed them to storm trenches easily. in world war 2 the Germans took what they learned from world war 1 and created a new form of warfare called blitzkrieg (lightning war) where tanks,planes, paratroopers and infantry attacked at the same time. France fell because the British and the French didn't learn the lessons world war 1 taught, they hid in trenches the Germans drove over them with hundreds of tanks and planes etc. Germany learned mobile warfare, Britain did not but won because they had 50+ countries on their side.
It revolutionized the world. Planes linked up the whole world and allowed warfare technology to be developed. Great question by the way.
