Union States Revenue Service

"The Revenue Service is responsible for collection of duties and tariffs by foreign merchant ships, as well as the defence of these ships from pirates, as well as capturing smugglers"

- A brief overview on the mission of the U.S.R.S

The Union States Revenue Service was a maritime law enforcement agency which was a branch of the Union of Earth State's Department of the Treasury, which handled the currency and economy of the nation, including the collections of taxes and tariffs. As a branch of the Treasury, the Revenue Service collected import duties, taxes and tariffs from foreign ships, and protected shipping and the coastline from pirates and smugglers.

The service typically operated smaller, faster ships than the Union Navy, which reflected the service's goal of preventing smuggling, a lot of smugglers preferring to use small, fast craft in an attempt to evade law enforcement shipping.

The service was founding following the formation of the Union in 81 BBY as a unification of all of the world's Revenue Services, because few nations still had a Revenue Service, instead letting the Coast Guard deal with such matters, the service was comparatively small.

In early 21 BBY 10 of the 59 nation states of the Traditionalist Faction, a political faction within the Union Senate which advocated the traditionalist mindset of the Union, that if a loose alliance of nations and Nation's Rights, rather than a centralised one, as was favoured by their opponents, the Federalist Faction, seceded from the Union and founded the Confederate States of Earth, within a few short hours after the Declaration of Confederate Independence government ships of the Union, including ships from the Navy, the Revenue Service and the Union States Coast Guard, as well as merchant ships, which had been crewed either with those born or raised in Confederate states, or Confederate sympathisers, had begun defecting to the Confederacy, which was the backbone of the young Confederate maritime fleet.
