Name two ISR assets used by the Marine Corps for expeditionary operations.

• A. Predator drones and E-2 Hawkeye
• B. MUAS and F-35B sensor suite
• C. P-8 Poseidon and MQ-9 Reaper
• D. A-10 Thunderbolt II and F-15 Eagle

Answer: (B)

For expeditionary ISR, the Marine Corps relies on a combination of unmanned systems for persistent, on-demand reconnaissance and the advanced sensor suite embedded in its fifth-generation fighter for fused, high-fidelity situational awareness. The Marine Unmanned A System (MUAS) provides portable, scalable ISR coverage in austere, rapidly deployable environments, allowing ground units to see over the next ridge or behind obstacles without risking aircrew. Pairing that with the F-35B’s sensor suite gives commanders access to fused, 360-degree awareness from onboard sensors like the distributed aperture system and advanced EO/IR, radar, and data-sharing capabilities, all integral to coordinting dispersed forces and targeting with speed.

Other options rely on assets outside the Marine Corps’ typical expeditionary ISR toolkit. Predator-type drones and the E-2 Hawkeye are not Marine Corps systems, the P-8 Poseidon and MQ-9 Reaper are Navy/USAF platforms rather than Marine assets, and the A-10 and F-15 are Air Force aircraft, not used as Marine Corps ISR assets.
