The tanks had to have a top speed on flat ground, be able to make sharp turns at top speed, have a reverse function, be able to climb hills, cross a 8 foot gap, and hold 10 crew members. The first tank was nicknamed 'Little Willie' and was first made when Colonel Ernest Swinton when he collaborated Ideas with Winston Churchill.
Richard Fiedler was the creator of the Flame throwers and they we're produced in Germany. The flame throwers were used to clear enemy soldiers from their front trenches. They first had a range of 25 meters but were later increaded to 40 meters.
The most significant exception to the concept of coastal activity was the German Deutschland class of merchant U-boats, each 315 feet long with two large cargo compartments. These submarines could carry 700 tons of cargo at 12- to 13-knot speeds on the surface and at seven knots submerged. The Deutschland itself became the U-155 when fitted with torpedo tubes and deck guns, and, with seven similar submarines, it served in a combat role during the latter stages of the war. In comparison, the "standard" submarine of World War I measured slightly over 200 feet in length and displaced less than 1,000 tons on the surface. Submarines were created by Cornelis Drebbel in 1620.
