Cassandra Moore

Colonel Cassandra Moore is the commanding officer of the NCR Army forces stationed at Hoover Dam in 2281.

Background
Moore volunteered for the NCR military at the age of 16. Despite some odd looks at first, she got top marks during her training and received an officer's commission at the age of 17. During this period, she took part in operations against various gangs plaguing the NCR territory, sharpening her skills on the likes of Jackals and Vipers, as well as surviving four tours of duty against the Brotherhood of Steel in California, and is widely considered to be one of the most skilled and accomplished commissioned officers in the NCR Army. She is a noted conservative in military matters, favoring strength and determination over cunning and diplomacy. Chief Hanlon says that she is "better at making graves than making friends."

Eventually, she was invited to join the New California Republic Rangers. She considers years spent in their ranks as the best of her life, doing something important and with the freedom to do it as she saw fit. She was forced to leave the Rangers after a major injury. Although she was subsequently promoted to colonel, a job which was less physically demanding, and given greater responsibility, she still misses those times, and she has never liked having to command from a desk.

Moore is not completely bitter, however; she recognizes that holding high rank means getting the chance to have a much wider-reaching influence over events than is ever possible as a junior officer. She considers having the power to have things done her way, without having to tolerate disagreements, as a perk. Her commanding style usually results in the earth being razed and fields salted, as Chief Hanlon puts it.

Personality
A war hawk, Moore displays unfailing support for General Lee Oliver and President Aaron Kimball's push to seize the Mojave - support which has seen her gain great influence - and considers strong action to be the best means of ensuring NCR's dominance in the region. She goes out of her way to neutralize or destroy groups and people that oppose the NCR in any way, such as the Great Khans, the Brotherhood of Steel, the Omertas and the Kings, whether it's in the NCR's interests, or because of her own personal grudges.

As such, any solutions that do not involve exterminating the Khans, the Brotherhood or the Kings will earn her ire; particularly if they include forging an alliance and/or peace. She speaks critically of Ambassador Crocker and his more diplomatic approach to NCR's expansion into Vegas and will vow to push back against him if the Courier chooses to support his approach to the Kings and Freeside above hers. Ultimately, Moore is well aware of her own greatest virtue as a soldier: she gets results, and her superiors care about that more than anything else.

Quests

 * For the Republic, Part 2: Colonel Moore tasks the player character with cleaning up the problems in and around New Vegas.
 * Kings' Gambit: Moore will tell you to tell the Kings to stand down or be destroyed and offers to send a squad to back you up.

Effects of the player character's actions

 * With a reputation of 'Idolized' with the NCR, Moore will salute the player character when they finish dialogue with her during the subquests contained in For the Republic, Part 2.
 * If the Courier sides with the NCR at the battle of Hoover Dam, one of Moore's orders are to destroy the Hidden Valley bunker. If the Courier chooses to pursue the diplomatic path, forging an alliance between the Brotherhood and the NCR will make her furious and the player character will gain NCR infamy. The amount, however, is negligible, and will not impact overall reputation with the NCR so long as the Courier has been in good standing with them up to that point.
 * Colonel Moore will disappear from the game world if the player character fails Don't Tread on the Bear! quest to prevent them from progressing further along the NCR questline; killing her will fail this quest instantly regardless of player character's reputation with the NCR.
 * If Colonel Moore dies, the whole NCR will become permanently hostile with the player character, regardless of the circumstances involving her death or the player character's reputation with the NCR.

Other interactions

 * When talking to her while the battle of Hoover Dam has begun she says that the NCR has driven the Legion to the east and the NCR are controlling the dam.

Appearances
Cassandra Moore appears only in Fallout: New Vegas.

Bugs

 * During How Little We Know, there is a bug where, after completing it, the game will not allow the player to talk to Colonel Moore. Possible cause: This happens when the courier hasn't spoken with Liza O'Malley at the beginning of the Omertas part of the For the Republic, Part 2 quest or if the player has already gotten You'll Know It When It Happens from Yes Man.
 * One could use console command that allows you to lie about Omertas and continue the chain.
 * Kill Cachino and lie to the NCR about their plans. The player will still get NCR fame and no evil Karma. This is the only way to fix the glitch and continue with the NCR.
 * During the quest You'll Know It When It Happens, Colonel Moore may be missing.
 * In the desk in her office is a key, grab the key from her desk (the player will get negative karma, but no fame loss). She should now appear to be walking into her office.
 * During the quest Oh My Papa, when speaking to Regis, one will receive an objective update to speak to Cassandra Moore about an NCR/Great Khan alliance. When trying to speak to her, there is no dialogue option to speak about it.
