The Patrol Investment Group, also known as the PIGS and the Security Guards, are a security firm featured in Grand Theft Auto: Vice City.

While superficially appearing nothing like a criminal organization, GTA Vice City describes members of the PIGS as a "gang", as evidenced by games stats, when the PIGS can be declared the player's "least favorite gang" if the player kills more PIGS members than those from other gangs. The stats also dubbed members of the PIGS "security guards".


The PIGs appear many times throughout the story of GTA Vice City. They provide protection for Congressman Alex Shrub and the band Love Fist, and have links to the Vice City Triads, providing protection for their illegal counterfeiting operation. At one point the PIGs attempt to move in on Tommy Vercetti's protection rackets in Ocean Beach; Tommy wipes out the guards involved, and destroys their office.


Unlike conventional gangs, PIGs do not congregate or move in groups, but rather patrol the streets separately. PIGs are not ordinarily hostile to Tommy, and will only attack in self-defense; PIG members will also attack the player if they fire a weapon, whether it was aimed at them or not.

PIGs patrolling Starfish Island may attack or be attacked by the Vercetti Gang if they enter the grounds of Tommy's mansion. Likewise, North Point Mall PIGs are frequently in conflict with the Sharks; police act against both parties when gun battles occur. In addition, policeman will pursue and kill PIG members in the same manner as they do with street criminals, allowing the player to attain "Good Citizen Bonuses" worth $50 each for each punch delivered to a fleeing PIG member
