Which combination does the Marine Corps rely on to sustain operations when access is contested?

• A. Prepositioned stocks, afloat prepositioning, and rapid resupply
• B. Strategic retreat and disbandment
• C. Only casualty evacuation measures
• D. Ad hoc improvisation without prepositioning

Answer: (A)

When access to supply routes and bases is challenged or denied, staying power comes from having supplies ready near the fight and a rapid way to replenish them. The Marine Corps uses a mix of forward-staged resources and flexible logistics to sustain operations without depending on vulnerable lines of communication. Prepositioned stocks sit at strategic locations so Marines can draw from them immediately, reducing the time to begin or sustain operations. Afloat prepositioning puts equipment and supplies aboard ships that can stay near potential hotspots, giving a near-instantable reservoir of gear without needing to sail through contested ports or airfields. Rapid resupply keeps fuel, ammo, parts, and other essentials flowing through air and sea channels as the situation evolves, ensuring momentum isn’t lost when conditions change. Together, this combination provides resilience, redundancy, and endurance in contested environments. In contrast, retreat and disbandment don’t sustain forces; relying only on casualty evacuation ignores the broader logistics needs; and improvising without prepositioning leaves critical shortages if routes become restricted.
