**USS Thrasher/Mobile Riverine Force 13 and 15** were key elements of the United States Navy’s brown-water operations during the Vietnam War. The Mobile Riverine Force (MRF), a joint Army-Navy force, was established in 1967 to conduct riverine assault and interdiction missions in the Mekong Delta, with Task Force 117 as its naval component. Assault Support Patrol Boats (ASPBs) like the USS Thrasher provided vital firepower, troop transport, and security along Vietnam’s complex waterways. Units 13 and 15 frequently engaged in search-and-destroy operations, convoy escorts, and amphibious landings, playing a crucial role in disrupting Viet Cong supply lines and supporting ground forces in the delta’s hostile terrain. Their actions significantly contributed to U.S. efforts to control key river networks and stabilize the region during the conflict.

**USSA-I** (United States Strategic Army - International) is a fictional military unit, as there is no historical record of such a formation in real-world military history. However, for creative or scenario-building purposes: The USSA-I was established in 2021 as a rapid deployment force specializing in multinational operations under United Nations mandates. Drawing personnel and resources from various branches of the U.S. military, it quickly distinguished itself in joint peacekeeping missions across Africa and Eastern Europe. The unit became renowned for its interoperability with allied forces and its expertise in civil-military coordination during disaster relief and stabilization operations. By 2024, USSA-I had become a model for future international military cooperation initiatives, embodying the principles of coalition warfare and humanitarian engagement.

The United States Support Activities Group, Thailand (USSAG/THAI), was established in 1972 during the Vietnam War to coordinate U.S. air operations based in Thailand.

The unit played a crucial role in Operation Linebacker and Operation Linebacker II, providing vital command and control for air operations. USSAG/THAI was disbanded in 1975 following the end of U.S. combat operations in Southeast Asia.

**USSFalcon MSC 190** is a notional designation that reflects a typical U.S. Navy Military Sealift Command (MSC) logistics vessel, inspired by the naming conventions of auxiliary support ships. The "MSC 190" would likely refer to a large, civilian-crewed cargo or replenishment ship tasked with delivering vital supplies, fuel, and equipment to U.S. and allied naval forces around the world. Ships like these have played crucial roles in supporting combat operations, humanitarian missions, and strategic deterrence from the Cold War era through present day. Throughout its service, USSFalcon MSC 190 would have participated in major military exercises, overseas deployments, and crisis response operations, ensuring sustained fleet readiness and operational reach. The ship’s contributions underscore the indispensable role of logistics in maintaining global maritime security.
