According to Star Wars lore, Imperial stormtroopers are human men and women who have been recruited (or conscripted) at a young age to serve as expendable foot soldiers of the Empire, gradually replacing clone troopers as their accelerated aging forces them to retire. These recruits are trained at Imperial Academies spread out across the galaxy where they undergo intense conditioning that instills fierce loyalty, strict discipline and ruthless efficiency while removing any sense of individualism or empathy. As the backbone of the Imperial Army, stormtroopers are dreaded for their brutality, carrying out atrocities in the name of Emperor Palpatine, and their fanaticism, engaging the enemy with no regard to casualties.
