Tanks: Differences in World Wars

Tanks were first used in a major conflict in World War I, where they were immovable juggernauts that could relieve some of the horrors of trench warfare. These were not very mobile, and had little success, as they had very little time for testings.  However, tanks were huge in World War II. Completely re-adapted to serve new roles, due to the genius of men like General George S. Patton, and Erwin Rommel, tanks became increasingly more important. All major nations sported their models of tanks. The British had the Churchill and the Cromwell; the Americans had the Sherman and the Stuar. The Germans had the Panzer series, the Panther, and the Tiger models. Even the Soviets had their T-Models (e.g T-38).
Tanks became mobile, support units in World War II. General Patton, who had been a member of the cavalry in World War I, is perhaps the most well known (and controversial) general when it comes to America and tanks. He fully remodeled the ideas on the weapons, and achieved great success with his new strategies. He greatly respected the German General Erwin Rommel, who Patton considered his equal and rival. Patton is well known for his North African campaign, his invasion of Sicily, and 'rescuing' the 101st Airborne Division from Bastogne, during the battle of the Bulge. Of course, if you've watched Band of Brothers, you know that every member of the 101st will, to this day,will claim that  they did not need to be rescued...
Tanks have survived the test of time thus far, and are still used in our military today. Tanks have been upgraded, and due to changes in types of warfare, have lost some of their earlier uses.
