The Misfits are appropriately named because of their lax behavior and lack of combat readiness. Sergeant McCredie is at his wits' end trying to train them, but he's determined to make them an upstanding group if it kills him... or them.
The player has the opportunity to whip them into shape during the quest Flags of Our Foul-Ups. Depending on the completion of the quest, the Misfits will either repel the attack on Camp Golf during the Second Battle of Hoover Dam or be courtmartialed by the NCR and executed.
Shaped up by the Courier's advice, The Misfits distinguished themselves during the Legion's attack on Camp Golf. Mags was finally promoted to Sergeant, and the rest of The Misfits received an official commendation. They continued to serve with distinction for many years.
Complete Flags of Our Foul-Ups, but with a Caesar's Legion victory at Hoover Dam.
The Misfits' laziness caught up with them when the Legion attacked Camp Golf. Those who weren't killed in the attack attempted to flee, but were caught at Mojave Outpost, court-martialed, and hanged from the ranger monument.
Do not complete Flags of Our Foul-Ups; or complete it with Poindexter's advice and a Caesar's Legion victory at Hoover Dam; or complete it with Poindexter's advice and complete the endgame quest All or Nothing for Mr. House.
Driven into a frenzy by their use of psycho, The Misfits inflicted heavy casualties on the Legion during the defense of Camp Golf. At first they were commended for their valor, but eventually, desperate for more of the chem, they turned on travelers in Outer Vegas. For their dishonorable conduct, the NCR court-martialed and executed them by firing squad.
