Among the listed aircraft, which has the highest ambulatory capacity?

• A. CH-53D Sea Stallion
• B. CH-47 Chinook
• C. MV-22 Osprey
• D. UH-60 Blackhawk

Answer: (A)

This question is testing how many walking wounded an aircraft can carry in a CASEVAC role, which depends mainly on interior space and how that space is arranged for patients who can walk or stand. The CH-53D Sea Stallion has the largest internal cabin among the options, giving it the most flexible room to accommodate ambulatory patients. Its long, wide cargo deck and multiple access doors let ambulatory patients line the floor or sit in seats with minimal crowding, while stretchers occupy less overall space. The other aircraft have tighter cabins or seating configurations more often used for litters or seated patients, which reduces how many ambulatory patients can be carried at once. So, in terms of walking-wounded capacity, the CH-53D offers the greatest capability.
