Their uniforms consist of tan-coloured tactical vests and woodland khaki camouflage fatigues, and their vehicles are colored tan. Their shoulder flash is a thunderbolt crossed with a sword.
Their base is Sierra Point, located between Downtown and New Colvin. Despite being stationed on a small island, they have large numbers and arsenal, including attack vehicles and a 2,000lb[reference?] bomb that is stolen by the Saints. The SNG is the fifth level of law enforcement before STAG's arrival, after which, STAG replaces them, and they are rarely present until the end of the story.
They appear in Saints Row IV operating in Virtual Steelport in the exact same locations they did in Saints Row: The Third. Similar to Saints Row: The Third, they attack Playa at any Notoriety level. In Kinzie's Loyalty mission "Kinzie's Adventures" they are being led by a virtual figment of Cyrus Temple and drive STAG vehicles.

They later pursue Jenny Jaros and Playa through Downtown until the Space Amazons intervene. Later the SNG attempts to gun down both Jenny and Playa during the final film sequence because Zhen purposely did not tell them that everything that's going on is all just part of another elaborate film scene.
