Which term is used for Marines operating on rivers with specialized craft for assault operations?

• A. MAGTF
• B. Riverine assault craft unit
• C. LAR
• D. Fixed wing attack

Answer: (B)

Riverine operations involve Marines moving and fighting along waterways using specialized boats designed for swift insertion, maneuver, and support along rivers. A unit built specifically to operate on rivers with assault-capable craft is described as a riverine assault craft unit, reflecting both the environment (riverine) and the mission (assault using craft). This term best fits because it directly names the setting and the method—riverine operations conducted with assault craft. In contrast, MAGTF refers to the overall Marine Air–Ground Task Force structure, not the riverine capability; LAR denotes a land-based, armored reconnaissance unit; and fixed-wing attack describes aircraft, not riverine amphibious craft.
