Fox Cannon
From Halopedia, the Halo wiki
The Fox Cannon was a UNSC vehicle cut from Halo Wars. It was to be a self-propelled artillery vehicle,[1] capable of firing five shells per minute, and with great accuracy due to satellite targeting over a distance greater than 50 kilometers. The Fox was equipped with a 175mm cannon that shot the M179 Projectile. Given its role, it was likely replaced by the Cobra.
