Secret Service (Fallout 2)

The United States Secret Service (or simply Secret Service) is a United States federal law enforcement agency operating under the auspices of the Enclave following the Great War, the organization succeeding the United States government.

Pre-War
Founded shortly after the American Civil War as part of the Department of the Treasury to combat the widespread counterfeiting of the US Dollar, the Secret Service later became a de facto federal police force alongside the United States Marshals Service until the creation of the Bureau of Investigation, the precursor of the Federal Bureau of Investigation, in 1908.

After the assassination of President William McKinley in 1901, the Service was informally asked by Congress to provide presidential protection, and in 1902 began providing full-time protection to the president. They continued in this role for over the next century and a half, up until right before the Sino-American War escalated into the nuclear exchange that came to be known as the Great War.

Appalachia
Shortly before the Great War the United States government quietly removed the gold bullion from Fort Knox to a new installation in Appalachia, Vault 79. By removing the gold from the well-known Fort Knox, the intent was to assist the re-establishment of government by ensuring that the federal reserve would be hidden from Chinese nuclear strikes, and survive for use by members of the Federal government. The Secret Service was placed in charge of protecting the vault and its gold reserves, along side members of the United States Armed Forces, with Derek Garrison acting as the agent in charge. This Secret Service has no relation to the Enclave.

New California
On the West Coast, the Secret Service was reorganized into a more suitable role for the post-nuclear era, but were still tasked with protecting the function of the government (most notably the President). Most infamously however, their mandate more often than not included their being deployed on delicate, stealthy, behind-the-scenes operations to the mainland, to silence entire outposts/bunkers of Brotherhood of Steel personnel, or to even air-drop intelligent deathclaws into/near Vault 13 via Vertibird.

The Secret Service is also on record as being deployed to retrieve and/or assassinate certain wastelanders, ultimately never leaving a single known living witness to spread the word of, or impede their missions.

Frank Horrigan was considered an elite and seasoned 'special'-rank agent of not only the Secret Service but proved himself to be one of the most deadly and infamous assets of the entire Enclave.

After the Destruction of Control Station ENCLAVE, the official fate of the Secret Service as a whole remains unknown, although it is plausible that remaining or surviving agents relocated with the rest of the Enclave away from New California, were killed in the explosion or managed to escape beforehand.

Appearances
The Secret Service appears in Fallout 2 and the Fallout 76 add-on Wastelanders. It is also mentioned in the Fallout Bible.

Behind the scenes
The Secret Service is based on the real world United States Secret Service (USSS).
