Under Armed is a side mission in Dead Rising 3.
Jamie calls about a man snooping around the Central City police department. Enter the police station through the underground parking area of the Los Perdidos Police Department to find a police officer named Dwayne standing outside of the armory. He is frustrated that he can't get into the armory because the person who has the key took off with it. He desperately wants to be better supplied.
He asks Nick to bring him a riot shield, a handgun and a grenade. After bringing those three items to him, he will then ask Nick to bring him a shotgun which will finish the quest. All of these items can be found in the police station. Alternatively, you can find them in a weapon locker if they've been picked up previously.
When Dwayne has been given all of the items, he will join Nick's party as a posse member. The armory is locked until Nick is able to get the key from a side mission during Chapter 5.
