"Second Level Security, prepare your defenses, he's coming your way."
Imperial officer referring to Galen Marek[src]

Second Level Security was an Imperial security unit of stormtroopers and riot stormtroopers that were stationed in a casino in Tarko-se on Cato Neimoidia. In 1 BBY, a clone of Galen Marek tore his way though the casino, easily defeating the Imperial troops in his way, including Second Level Security troops.
