Which function of the USAF supports land and naval forces?

The correct answer highlights the crucial role of airlift and airborne operations in supporting land and naval forces. These operations enable the rapid movement of troops, equipment, supplies, and other resources to areas where they are needed, which is essential for the success of ground and maritime operations. Airlift capabilities can provide vital logistical support, ensure the timely deployment of forces, and facilitate operations in scenarios where traditional ground transport may be impractical or delayed.

Airlift and airborne operations also encompass the ability to conduct strategic and tactical air drops, enabling forces to reach isolated locations or to aid in humanitarian efforts. This flexibility and responsiveness significantly enhance the operational effectiveness of joint military operations involving land and naval partners.

The other options do not primarily focus on the support to land and naval forces. Development of tactical weaponry pertains more to the enhancement of direct combat capabilities rather than logistical support; joint space operations focus on the integration of space-based assets for broader military objectives; and counter-terrorism strategies address specific threats rather than the general support needed for conventional land and naval forces.
