While Arizona was mostly under NCR control with the fall of Phoenix in fall 2282, ex-Legion raiders would continue to be a threat in the area for years to come.Ī couple months prior, Caeser's Legion had launched a second assault on the Hoover Dam seeking to take over the instilation. After the fall of Nova Roma, NCR and Allied forces attacked remaining Legion strongholds in the Magna Chasma (Grand Canyon) region to the north and the cities of Two Sun (formerly Tuscon) and Phoenix to the south. In summer, 2282, the NCR and allied forces would take the Legion capital of Nova Roma (formerly Flagstaff), and the Third Caesar of the Legion, Aurelius of Phoenix. Newly allocated forces included mechanized and armored forces, which would prove devastating against the Legion, who had little armor or anti-tank weapons.

The offensive was facilitated by greater allocation of forces and resources to the war against the Legion thanks to the cessation of hostilities with the West Coast chapter of the Brotherhood of Steel in the Treaty of Lost Hills. The NCR Arizona Offensive was an offensive conducted by the New California Republic Defense Force and allied factions, including New Vegas, The Brotherhood of Steel, the Dead Horses, the Boomers, and various rebel slave and anti-Legion insurgent factions, during in the latter stages of the NCR-Legion War in 2282. 15 Vertibirds (most destroyed on ground at Nova Roma).2 F-108 "Rapier" Fighters (NCR Air Force).61 Vertibirds (40 NCR, 20 Brotherhood, 1 Enclave Remnant).~300 assorted artillery pieces (35 Boomers, remainder NCR Army).~200 robots (including 50 New Vegas Securitrons).
