Which of the following represents a Mobility Force Aviator aircraft?

The KC-135 Stratotanker is a prime example of a Mobility Force Aviator aircraft. This aircraft is primarily used for air refueling and plays a crucial role in extending the range and endurance of various military aircraft, enabling them to carry out missions without needing to land for fuel. The KC-135 is part of the air mobility system, which focuses on the strategic deployment of forces and logistical support, making it an essential asset for rapid military operations and enhancing joint service capabilities.

In the context of the other aircraft listed, they serve different purposes. The EC-130/37 is primarily an electronic warfare aircraft, focusing on communication and intelligence gathering. The RC-135 serves as a reconnaissance aircraft, designed for intelligence collection. The U-28 is a special operations aircraft used for various missions such as counter-terrorism but does not primarily serve the role of a mobility force. Thus, the KC-135 stands out as the correct representative of a Mobility Force Aviator aircraft.
