The United States Marshals Service (USMS) is a federal law enforcement agency in the United States. The Marshals Service serves as the enforcement and security arm of the U.S. federal judiciary, although it is an agency of the U.S. Department of Justice and operates under the direction of the U.S. Attorney General.[4][5] It is the oldest U.S. federal law enforcement agency, created by the Judiciary Act of 1789 during the presidency of George Washington as the “Office of the United States Marshal”.[6] The USMS as it stands today was established in 1969 to provide guidance and assistance to U.S. Marshals throughout the federal judicial districts.

There was something about it which meant that it could be used to bridge gaps between MIL + FEDs ... IDK + TBD but it continues to strike me. Also, remember, right before JoePedo inauguration in 2021 a slew - I think 3000 - new US Marshals were sworn in.
