Vault Lasers is a mandatory prep mission featured in Grand Theft Auto Online as part of the The Diamond Casino Heist update. It is a freeroam mission needed to progress The Diamond Casino Heist. Completing this setup gives players laser drills to open the vault during the Silent & Sneaky approach.
Military[]
Description[]
Lester informs the player that there is a shipment of vault lasers surrounded by a group of military personnel and that the player must go in and take them. This can be in places such as El Burro Heights or the Grand Senora Desert.
Once there, the military are immediately hostile and the player will receive a 4-star wanted level, so the player must fight them off and collect the two drills. Once the player has lost the cops and both drills are delivered to the Arcade, the mission is complete.

Cliffford Mercenaries[]
Description[]
Lester informs the player that there is a group of Cliffford Mercenaries, including one Juggernaut, who have the lasers in their possession and that they need to go steal them. The mercenaries can be in places such as the Palmer-Taylor Power Station or Zancudo Treatment Works.
Once there, just like the Military variant of the mission, the Cliffford Mercenaries outside are immediately hostile, so the player must kill all of them before proceeding inside their warehouse. However, no wanted level will be applied. Once inside, there are a few more mercenaries the player must kill before stealing the lasers and delivering them to their Arcade. Once both lasers are delivered, the mission is complete.
