As the hub of the Marine Corps' prepositioning programs, Marine Corps Support Facility Blount Island (MCSF-BI), located in Jacksonville, Florida, serves as the home of Blount Island Command (BICmd) and its worldwide mission of supporting the Fleet Marine Forces (FMF) who are Forward deployed and forward engaged.

Stockpiles of United States Marine Corps weapons, vehicles, ammunition and other equipment have been located in Norway since 1981 as part of what is currently designated the Marine Corps Prepositioning Program-Norway (MCPP-N). This material is stored in a network of climate-controlled caves and buildings near the city of Trondheim, and is drawn upon as part of worldwide US military operations. Norway has met most of the costs of the MCPP-N since the 1990s, and the sites are mainly staffed by Norwegians.
