Ryder

Ryder's last job: hit the National Guard depot at Ocean Docks. CJ keeps lookout from a forklift while Ryder loads crates of military hardware onto a Mule truck.
Robbing Uncle Sam is the final mission in Grand Theft Auto: San Andreas given to protagonist Carl Johnson by Grove Street Families member Lance "Ryder" Wilson from his home in Ganton, Los Santos, San Andreas.
Carl goes to see Ryder in his back yard, who is smoking. He asks Carl why he, himself, didn't finish high school. After Carl asks if it was because he dealt drugs since the age of 10, or if it was because he attacked a teacher for wearing Ballas colors, Ryder responds that it's because he is too intelligent. After asking Carl where they can attain guns, Ryder informs him that the National Guard has all of the guns.
Carl and Ryder get inside of a Mule (delivered by LB), and drive to the National Guard Depot at the Ocean Docks. Once they arrive, they notice that the gate is closed. Carl climbs over the wall and shoots the switch to open the gate. Ryder drives the Mule to a weapon's warehouse, where Carl shoots the switch to open the door. Ryder stands guard as Carl collects 6 crates of weaponry inside and around the warehouse using a forklift.
The crates can be destroyed by shooting, attacking, or running over them by a human races. They may contain a Pistol, a Micro SMG, a Shotgun, Grenades, a Health pickup, or a Body Armor. However, if the player destroys too many of the crates before loading at least six crates into the truck, the mission will fail.
Once 6 crates have been collected, Carl and Ryder escape from the National Guard, who pursue them in 2 Patriots. They then drive back to Emmet's in Willowfield.
