WORLD HISTORY

Detailed explanation-1: -Heavy artillery, machine guns, tanks, motorized transport vehicles, high explosives, chemical weapons, airplanes, field radios and telephones, aerial reconnaissance cameras, and rapidly advancing medical technology and science were just a few of the areas that reshaped twentieth century warfare.

Detailed explanation-2: -World War I popularized the use of the machine gun-capable of bringing down row after row of soldiers from a distance on the battlefield. This weapon, along with barbed wire and mines, made movement across open land both difficult and dangerous. Thus trench warfare was born.

Detailed explanation-3: -It would be “Cannons” that does not represent advances in technology during World War I, since in fact cannons had been used in warfare for quite some time before this.

Detailed explanation-4: -Inventions like synthetic rubber, the jeep, the atomic bomb, and even duct tape helped the Allies win World War II by allowing their militaries to wage war on an overwhelming scale.

Detailed explanation-5: -Trench periscopes, consisting of an angled mirror extended beyond the top of a trench, allowed soldiers to see above the trench without being exposed to enemy fire. This ‘pocket’ periscope was collapsible for easy storage and transport. It was not standard issue and had to be individually purchased.

Detailed explanation-6: -Airplanes and submarines were used for the first time, initially to locate the enemy. Field telephones and sound equipment was also used to find the enemy’s location. Still, some new weapons and technology used such as chemical warfare, flamethrowers and submarines caused great fear and chaos during World War I.
