Summary
Covenant Elite. He is described as a "veteran," which is consistant with the covenant rank of "Major" and red armor to match.
He is stationed on Installation 04 in 2552, and becomes part of the detachment of Covenant soldiers stationed at the crash site of the Pillar of Autumn under 'Ontomee. When Zuka 'Zamamee arrives at the ship under the alias of "Huki 'Umamee," 'Kasamee looks at him with respect for his vigor in wanting to hunt down the Master Chief. 'Kasamee is never able to tell this to the SpecOps Elite, though, because 'Zamamee tries to avoid being discovered as much as possible and never talks to him.
NOTE: It is assumed that he has a "first" name like all other Elites, but it is never mentioned.
