After The Black Rider is eliminated from Greendale's 2011 Paintball Assassination tournament, the school is invaded by Paintball Commandos. Leading them is the sponsor of the tournament, Pistol Patty, who reveals herself to be none other then Dean Spreck from City College. Hoping to destroy Greendale College for good, he offered a $100,000 cash prize to the students knowing it would result in them trashing their own school. Spreck then used his army of commandos to eliminate any remaining students from the competition and complete the school's destruction. Their first appearance was in the two part Season Two finale "A Fistful of Paintballs" and "For A Few Paintballs More".
The City College Storm Troopers all outfitted with the same white jumpsuit, white knit skull caps, black combat boots and equipped with the same paintball paraphernalia. Unlike the Greendale students, they also have paintball protection gear including goggles, tactical vests, front harnesses as well as elbow and knee pads. They also use a comm system and are in constant contact with Dean Spreck to carry out his orders. The handheld weapons they use seem to be the Empire ER3 Marker model with paintball loaders attached. Other equipment they use include a gatling gun and remote controlled cars equipped with various payloads such as a grenade.
