The start of World War II prompted countries to make large technological advances. With the war raging all around the world, and more and more countries entering the fray, it was especially important for governments to continue to develop new technologies to get a step up on their opponents. Many new weapons, vehicles, and ways of communication were developed and used against the Axis of Power. In today's modern wars, many of these technologies have been improved and are still used in the United States Armed Forces. Still, there is debate on whether or not these new technologies were used properly and humanely during World War II and there modified counterparts in today's society.
The introduction of automatic guns in WWII led to a change in warfare. The reloading problems were solved by larger clips of bullets and a soldier could attack a larger object or group of soldiers easier. The use of the bazooka allowed soldiers to attack tanks and buildings without setting up demolitions and prevented more casualties since the range allowed soldiers to keep a safe distance.
Tanks were used during World War I but were not as advanced as they were in the second. Most of the tanks had radios which improved communication between each other. The tanks themselves were equipped with more armor to protect against the advancing guns. Tanks were also equipped with artillery and assault guns. Turrets gave tanks a very efficient main gun which could attack other armored objects and tanks.
World War II was the first war that was won in the air. Precision bombing and high-power guns made ground targets more vulnerable and easier to hit. Dog fighting became a major part of the war and won many battles for the US. Planes became more streamlined and the days of the bi-plane were gone. Better engines and plane structures allowed pilots to reach higher speeds and cover more ground.
