- "Gruppe Sechs provides private security services and offers failed cops a second chance to enforce the law on their own terms."
- ― Description at LCN.com.
Gruppe Sechs (or Gruppe 6) is a private security company featured in the Grand Theft Auto franchise since Grand Theft Auto III, with the exception of Grand Theft Auto: San Andreas. The player can buy stocks from them at the Lcn-exchange.com website in Grand Theft Auto V.
The "Gruppe Sechs" name (German for "Group Six") is a pun on both the infamous British security company G4S and the phrase "group sex". In GTA IV, the company's written logo is changed to "Gruppe 6", although this would still translate to "Gruppe Sechs" in German, and the company's vehicles still feature "Gruppe Sechs" logo in much smaller print on various surfaces. The name of the van, Securicar, seems to also serve as parody to G4S or "Group 4", since they were formally known as Group 4 Securicor. Despite those references, the company can be seen as the equivalent to American security companies such as Brinks, based on their very similar vans in GTA IV.
As indicated by markings on the Securicar, Gruppe Sechs have partnered with the Bank of Liberty, and is "licensed and authorized" to use deadly force. However, they never use deadly force and do not become hostile to the player in Grand Theft Auto IV. In Grand Theft Auto V, they will open fire on the player if they attack a Securicar.
In GTA IV, the Gruppe Sechs headquarters are located in Leftwood, Alderney on Long John Avenue, directly opposite to the Westdyke Memorial Hospital. There is also a Gruppe Sechs depot in Berchem, Alderney on Aspdin Drive. However, no Securicars can be found there on any of the various parking lots. Gruppe guards wearing green uniforms do appear in the co-op mission Bomb Da Base II, protecting a Gruppe Securicar from an ambush by players. It's unknown why the same models are not used in other modes. Gruppe Sechs has their own bank all over Alderney.
In Grand Theft Auto V and Grand Theft Auto Online, Gruppe Sechs personnel can be seen driving around in the Stockade. During Survival, they will drive Sandkings and first generation Cavalcades, while they also come in helicopters, regardless of the survival's main enemy team.
There are two types of uniform for Gruppe Sechs employees in Grand Theft Auto V.
Drivers wear a green shirt with the Gruppe Sechs logo embroidered onto the right sleeve while the U.S. flag is on the left sleeve. They wear a bulletproof vest accompanied with a radio and a belt, which includes a weapon holster and ID card. They wear black trousers with a green stripe down the side and black shoes.
Security guards, as seen in places such as the Richards Majestic, wear a white shirt with green trousers accompanied with a radio and a belt, which includes a weapon holster, black shoes and a tan cap carrying the Gruppe Sechs logo.
- The De Santa residence is protected by Gruppe 6 Armed Response, as well as various mansions. They are never seen defending the house, however, even when it is raided by Merryweather.
- There is a Gruppe Sechs padlock in a container in Fort Zancudo.
- The Gruppe Sechs security uniform is unlocked for Michael and Trevor if the player finishes the Big Score using the Subtle approach. No matter what type of approach the player choose, the uniforms are still available.
- There are Gruppe Sechs surveillance cameras on most of the stores, gas stations and businesses around Los Santos, including Lester Crest and Michael's house.
- If the player calls Merryweather for Air Support in GTA Online, Gruppe 6 men will come in an unarmed Buzzard.
- In Grand Theft Auto V, Gruppe 6 security guards are unique from other NPCs in that they can survive headshots from weaker weapons such as the Pistol.
- Their logo of a padlock is meant to be a parody of the number 6, and is incorporated into their company name just like G4S, their real life counterpart.
