Flood Jackals

The Flood Jackal Form is a Flood form present in Halo Wars. A flood Jackal is simply a Kig-yar that has been infected and become a combat form. They are known to use plasma pistols, plasma rifles, and Covenant Carbines.

While Jackals are not ideal hosts for Flood, they apparently are far from being immune to infection, as witnessed in Halo Wars.
