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.

The rest of her team decided to try and avenge her death by killing her killer. Yeah, thats right lads, spread the hate. They failed bitterly because the guy who killed Kat (whoever that may be) was in a Phantom high above the ground, and all they had to shoot with was an Assault Rifle cache and Kat's magnum. They wasted about five clips before the driver of the Phantom got sick of laughing and flew away.

Kat's body was tossed into the abyss that is New Alexandria, to be burned along with the rest of the city. To this day, no-one knows who killed Kat or what species/rank they were. However, there are a few clues. Whoever killed her must have been a high enough rank to be given a Needle Rifle (even though its crap) and they must have been a crack shot with it. So, a high-ranking sniper who is a great shot, likes shooting from a distance, is a resourceful and tenacious warrior but a complete coward and a hater. We can therefore conclude that Kat's killer was in fact.... Jun.

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