Drebin 893, unofficial arms dealer and gun launderer. Following the introduction of the Sons of the Patriots System, he and the other Drebins began selling weapons around the world to unregistered groups such as smaller PMCs and local militias, becoming the only individuals who deal in laundered weapons. They also sell various parts obtained through AT Security, as well as the fixing of records through personal connections.

They sell naked guns from before the SOP System; switch the ID chips in ID guns for fake chips; sell non-ID guns not requiring an ID process; and also offer gun parts and ammo. Drebin (893) approaches Solid Snake and proposes a mutually beneficial relationship—Snake provides weapons he finds on the battlefield to Drebin, and in exchange, Drebin will provide Snake with weapons he needs and unlock ID guns. They use units of barter called Drebin Points (DP) in lieu of currency. The Drebins' business comes from these relationships with green collars having no affiliation.

Drebin (893) is a fan of extinct and rare animals, UMAs, and famous soldiers throughout history. His hobby is collecting information on units like the Cobra Unit, Dead Cell, and the BB Corps, and has decorated the walls of his armored car with their photos. He keeps a pet monkey named Little Gray. His armored car is also equipped with OctoCamo, allowing it to disguise itself in emergencies. Likes to drink the carbonated beverage NARC, keeping a vending machine stocked with it inside his car.
