From Halopedia, the Halo wiki
He is featured as a mini-boss in the Spartan-IVs' Warzone training simulations. The Officer is a boss to appear on multiple maps in Warzone , and drives a Sword Wraith. The Wraith is painted red and has increased accuracy and health from a usual Wraith. His Wraith cannot be boarded or hijacked. However, if it is disabled multiple times with an EMP, the Officer will exit the Wraith to fight with a storm rifle and grenades. His empty Wraith cannot be driven. Killing one will give the team 25 VP, and earn the player a Boss Takedown medal. The gunner of the Wraith is an Elite Commander, while the Officer himself is a red Elite Warrior. It can be assumed that the title is below that of the Wraith Captain.
