Argent V missile

"These missiles are specialized to target and deliver their warhead to an aircraft with great speed and maneuverability. The missile pods are quite large and can be reloaded via a mechanical system in the Wolverine, which stores a small supply of missiles on board."

- Halo Wars.com description

Argent V missiles are surface-to-air missiles (SAMs) capable of destroying both surface targets and aircraft. These missiles are usually mounted on the MAAT-9 Wolverine anti-aircraft vehicle and the Vulture gunship.

Mendez was known to mount a rack of these missiles on his personal Warthog, back when he was training the SPARTAN-II's on Reach as a Chief Petty Officer.
