Kat
Catherine is described as an inspired tactician and an exemplary combatant, but also a brilliant cryptanalyst and a hacker; allegedly, there has not been a system yet that she has been unable to crack. According to Colonel Urban Holland, she has a habit of occasionally investigating classified Intel more than her superiors would like her to. Her ability to acquire and digest information has been described as "supernatural"; more than once, she has been able to read a situation, working with information many would find overly limited.
Much like Carter, Kat blames herself for Thom-293's death while it was apparent that neither was responsible; according to Colonel Urban Holland, Thom died because he pursued a group of enemies by himself rather than waiting for backup.
Kat's death can be attributed due to a fatal lack of situational awareness. Like the loss of her right arm in a previous operation, Kat underestimated the gravity of her situation and failed to initiate her armor's shielding system. However, another explanation could be that excess radiation from the nearby Covenant glassing shorted out her shields, as she may have been exposed to the radiation longer than the other members of Noble Team. Her trademark curiosity could also be blamed, as she was preoccupied at the time with understanding new uncharacteristic orders from Holland. Trading questions with Carter as to Holland's motives, she was too lost in her own mind as she analyzed this new information to focus on the present.
