When The Cayo Perico Heist update was released, this mission was removed due to its proximity to The Music Locker entrance.
Department of Defense was a Casino Work mission featured in Grand Theft Auto Online as part of The Diamond Casino & Resort update. It was a freeroam mission given to the player by Agatha Baker. It is no longer available probably because of its location interfering with the Music Locker entrance.
Description[]
Ms. Baker nervously informs the protagonist of a group of mercenaries that are trying to storm the casino and tells the protagonist to get rid of them as quickly as they can.
The player is tasked with going to the casino. When they arrive, they have to take out a group of Professionals on the east side of the casino. Care should be taken as they are heavily armed, and have a Technical.
Once the mercenaries are taken care of, Agatha will call the protagonist to inform them of a Speedo leaving the area, and instructs them to follow it to the enemy's base of operations.
Once the van is tailed to the destination, located in Burton, La Mesa, or Strawberry, the player is instructed to take out the leader - sporting Ballistic Equipment and armed with a Minigun - and all other mercenaries. Once all enemies are killed, the mission ends and Agatha calls the protagonist to thank them for their help.
