Which of the following is listed in the A-10 Ordnance as a type of air-to-ground ordnance?

• A. MK-82, 84, 77 / 10
• B. AIM-9M A2A missiles
• C. 1150 30 mm HEI rounds
• D. AIM-9M A2A missiles

Answer: (A)

Air-to-ground ordnance means weapons designed to hit targets on the ground, not aircraft. The Mk-82 and Mk-84 are standard general-purpose bombs, and the Mk-77 is napalm—classic air-to-ground bombs the A-10 is equipped to drop on ground targets. Those types are explicitly listed as air-to-ground weapons because they are intended for ground engagement.

In contrast, AIM-9M missiles are air-to-air, built to attack other aircraft, so they don’t fit the air-to-ground category. The 1150 rounds of 30 mm HEI are ammunition for the GAU-8 Avenger cannon; while the gun can contribute to ground attacks, its rounds are considered gun ammunition rather than a dedicated air-to-ground ordnance category. Therefore the combination of Mk-82, Mk-84, and Mk-77 best represents air-to-ground ordnance for the A-10.
