Dagger Squad is one of the best and most famous Brotherhood squads. They captured one of the leaders of the plot against mayor Chris Avellone and the ghouls in Springfield. After Latham was killed in Osceolla, Dagger Squad patrolled the area hunting mutant stragglers. When the Warrior's squad attacked Canyon City they, along with Tusk Squad, eliminated two of the Calculator's robot repair stations to the Northwest. Later Dagger Squad accompanied the Warrior's squad during the attack on the Calculator's base, Vault 0.
