Cassandra Moore

Colonel Cassandra Moore is a Californian commanding officer for the NCR stationed at Hoover Dam.

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 made officer at 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.

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 and given greater responsibility, she still misses those times.

However, she does find certain perks in the job, such as having the power to have things done her way, without having to tolerate disagreements. And since she's better at making graves than friends, her way usually results in the earth being razed and fields salted, as Chief Hanlon poetically puts it.

Moore is widely considered to be one of the most competent military officers in the Army and a veritable legend among NCR troopers, in no small part due to her surviving four tours of duty against the Brotherhood of Steel in California.

Personality
Moore displays unfailing support for General Lee Oliver and President Aaron Kimball's push to seize the Mojave – a 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 neutrilize 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 is a noted conservative in military matters, favoring strength and determination over cunning and diplomacy. Chief Hanlon notes that she is "better at making graves than making friends".

Quests

 * For the Republic, Part 2: Colonel Moore tasks the player 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.

Other interactions

 * With a reputation of 'Idolized' with the NCR, Moore will salute you when you finish dialog with her during the sub-quests contained in For the Republic, Part 2.

Effects of the player's actions

 * If the Courier chooses to pursue the diplomatic path, brokering an alliance between the Brotherhood and the NCR, this will make her furious and the player will gain NCR infamy. The amount, however, is negligible, and will not impact the overall reputation with the NCR so long as they have been in good standing with them up to that point.
 * Killing Colonel Moore will lead to the NCR branding the Courier a terrorist and all military personnel turning hostile as if the player had sided with the Legion.

Behind the scenes

 * When gameplay was slated to continue after the Second Battle of Hoover Dam, should the NCR have been victorious, Moore would have replaced Colonel James Hsu at Camp McCarran as a newly promoted Brigadier General and would relay that NCR forces secured the Mojave with little resistance and trade would reach an all-time high.

Bugs

 * During How Little We Know, there is a bug where, after completing it, the game will not allow you to talk to Colonel Moore. POSSIBLE CAUSE: This happens when you haven't spoken with Liza O'Malley at the beginning of the Omertas part of the For the Republic, Part 2 quest or if you have already gotten You'll Know It When It Happens from Yes Man. You could use console command that allow you to lie about Omertas and continue the chain.
 * PS3 solution: Kill Cachino and lie to the NCR about their plans. You will still get NCR fame and no evil karma. This is the only way to fix the glitch and continue with the NCR.
 * If the player sides with the NCR during the Second Battle for Hoover Dam, she has a large list of post-end game dialogue options. Telling the player about things after the Second Battle for Hoover Dam is over while actually playing through the Second Battle, noting that she was promoted to Brigadier General, has sent troops after the fleeing Legion Army, and how the Legion is falling apart because of their leaders being dead. This is more than likely because the game was at one point open-ended, with Obsidian only making the decision to exclude a postgame after development had already started.
