Secret Service (Fallout 2)

Main article: Enclave Armed Forces organization

The United States Secret Service (USSS) was law enforcement agency responsible both for protection of state secrets and the President’s protection. Before the War Secret Service could be the part of the United States Department of Treasury, as well as other law enforcement agencies. After the War USSS could became a part of the Enclave armed forces or just cooperate with them. The only proof, that Secret Service could be part of armed forces is Fallout Bible statement, that USSS agent Frank Horrigan has always been loyal to the armed forces (however he was a troop for some time also). Concerning cooperation with the armed forces, according to Fallout Bible:
 * there were soldiers, who wanted to accompany Horrigan on his missions, or witnessed some murders or tortures commited by him (eg. Sgt. Granite),
 * during execution committed on “farmers” family at the beginning of September 2241 Horrigan was accompanied by two the Enclave guards,
 * Horrigan was present during Vault 13 seizing by verti-assault squads also.

Frank Horrigan was the only known US Secret Service agent. USSS agents protected Executive Office (according to President's seretary floats and dialogue with the President) and could be presidencial bodyguards also. They were probably equipped with Advanced Power Armors.

During simple assassinations Horrigan was accompanied by 2 troops equipped with Advanced Power Armors and miniguns. During deathclaws' community extermination at Vault 13 he was by accompanied 5 troops. It is significant, that Horrigan and his troops didn’t hesitate to enter Shi’s part of San Francisco.

USSS organization:
 * possible person in charge, some office,
 * agent Horrigan as its main field executive force and leader of detached to Secret Service armed forces squads or teams,
 * some presidencial bodyguards (who could be called "guards" also by the President).

USSS had another system of ranks or positions then Armed Forces also ("agent" position present).
