Kat

Kat is a bitch with one arm who is the 'techie' of Noble Team. She hates everyone and has never witnessed a glassing before, and yet she likes Covenant for some reason. She doesn't like them as much when one of them shoots her in the head, with the crappiest replacement for the Covenant Carbine ever devised, but she's too dead at that time to care.

Carter, the leader of Noble Team, was so depressed by her death he rammed himself into a Scarab.
