C.R.A.S.H.

C.R.A.S.H. sends CJ to a Russian/Ballas weapons exchange at the Ocean Docks warehouse to seize a crate of guns and torch the rest of the contraband.
Gray Imports is a mission in Grand Theft Auto: San Andreas given to protagonist Carl Johnson by C.R.A.S.H. officers Frank Tenpenny, Eddie Pulaski and Jimmy Hernandez from the Jim's Sticky Ring doughnut shop in Market, Los Santos, San Andreas.
Carl goes to the Ocean Docks Freight Depot, where the Ballas and Russians are having a deal. He needs to get in the office where the deal is taking place, so he fights through the Russians, all armed with SMGs and Pistols, enters the warehouse by destroying the keypad, and fights through more Russians and Ballas on the way to the office. He finds the experiment Russian lab office, where two Ballas and the dealer are waiting for him. He kills the Ballas and follows the dealer, who runs outside, past many more Russians. Carl gives chase, and if he doesn't kill the dealer immediately, he enters a Banshee, with Carl following on a PCJ-600.
The dealer drives out of the depot and down the storm drain across the street. After exiting the drain in Commerce, the dealer proceeds through Pershing Square, after which his path becomes random. The mission is completed when Carl kills the dealer.
