Stormtrooper

Stormtroopers were the Empires elite troops, they were used to capture planets when destruction was not an option.

Training
Most Stormtroopers were innocent men recruited by the empire using cruel recruitment methods, but only stupid and foolish men were seduced by these methods so most Stormtroopers weren't very smart and none of them could shoot strait. Because of this fatal flaw more than 50% of all recruits died during "training accidents," most of these accidents involved one Stormtrooper accidentally shooting the man next tom him instead of the target right in front of him. Some accidents were caused by troopers that did not know how to use grenades and accidentally set one off in their barracks, killing all recruits inside. This is why the barracks were small, there was only room for ten troopers in each barrack. Which is most likely the smartest thing the Empire ever did. The recruits that survived the training were given a white armored suit in which they could barely move and they would be sent to fight the rebellion.

Fighting the Rebels
Many, if not all, Stormtroopers died fighting the Rebels. The life expectancy of a normal Stormtrooper, after said trooper had made contact with the rebels, was about 10 minutes. These ten minutes also included the time it would take for the landing craft to reach a planets surface or the time it would take to blow open the door of a rebel ship. This meant that a normal Stormtrooper had about 5 seconds to live after the first Rebel had seen him.

There were of course exceptions to this rule, one such exception occurred when Darth Vader ordered a group of Stormtroopers to capture princess Leia. Lord Vader was able to "properly motivate" his troopers by killing half of them and telling the other half he would kill them too if they didn't bring back the princess alive.
