The Merryweather Security is an organization featured in Grand Theft Auto V and GTA Online.
Merryweather Security is a "private military and security company" that appears as a main antagonist group in Grand Theft Auto V.
It is actually a mercenary group, divided in several divisions, determined by the uniform and equipment they carry:
- a Security Division (similar to Gruppe Sechs), using Merryweather Dilettantes and walking with guard dogs.
- A paramilitary force division, consisting of operatives trained for high-risk tasks, wearing heavy equipment and weaponry.
- Chem Security, seen operating around the Humane Labs and Research.
They appear in several missions and are central in the game's storyline, being tough enemies for the three protagonists.
