Strike Force Alpha was an Imperial brigade active from 0.5 ABY to 2 ABY during the period of the Krantian Civil War. This brigade, primarily made up of stormtroopers, launched an assault on the Rebel Alliance's Ghost Base located on the planet Krant. This attack occurred after the Empire discovered that a Bothan spy known as Utric Sandov was scheduled to meet with Rebel operatives at that location. An attempt to stall Strike Force Alpha was made by a Rebel officer, but the strike force successfully seized control of the base. Subsequently, they established their own military encampment within the remnants of Ghost Base, utilizing ASP-7 labor droids. However, Utric Sandov, along with the base's personnel, had already evacuated to a nearby island called Le'Roche. Subsequently, a Rebel army led by the exiled Jedi Echuu Shen-Jon and Princess Leia Organa destroyed Strike Force Alpha's base, effectively ending the Imperial strike force's existence. Palpatine's dark powers warped their minds, causing them to commit suicide if a Jedi attempted to convert them.
The strategy guide for the 2001 video game Star Wars: Galactic Battlegrounds was the first mention of Strike Force Alpha. The unit was officially named within the game itself, specifically during the second mission of the Princess Leia campaign. This campaign was also included in the game's 2002 expansion, Clone Campaigns.
