Three new weapons or methods of warfare first used during world war i and analyze what effect the introduction of this new technology had on america’s entry into the war and our ability to our allies achieve victory. guys

1) Machine gun: The machine gun is regarded as a WW1 technology, because they had the technology to make it work. The Machine gun was able to fire hundreds of rounds a second, and could cut down human waves quickly. The Allies were able to win with this, because they could stave off the Central Power attackers when they tried to take over Paris, and were able to mass produce them when the US joined the war effort.

2) Air warfare: Planes were generally used for the first time in war, and, in the beginning, was generally used for reconnaissance.However, people found out how to add machineguns onto the planes, and 'dogfights' started, as well as air support. The US was able to produce planes for the Allies and helped them win the war.

3) Tanks: The US was able to produce the first fully-rotating-turrent, and were also able to change how tanks were used during the war (after British invented it).  In the beginning of tank warfare, tanks were used more of a trench-warfare breaker, and were used in small numbers. After the US entry, tanks were used more and more, and being able to turn turrents instead of the whole tank allowed more mobility and faster change to destroy enemy units.

hope this helps

Farm land would be my guess
