NCR Military

Army Size
Two estimates put the army size around 30,000. One, using deployment cycles and casualty ratios, determines that the army size is ~32,000. The other, using commander-to-force ratios, concluded at around 25,000. A full muster like the one in 2241, perhaps 40% of the population when including womens' total equality in service, could be up to a million should the need for a full muster arise, i.e. the Legion's crossing of the Colorado.

The total probable size of the NCR military shouldn't currently exceed ~3% in active service, or about 80,000 troopers.

NCR Troopers
Most troopers will receive a refitted M16 rifle as their armament. In the way of armor and clothing they receive a khaki tunic and breeches, under hardened leather body armor, pauldrons, and boots. Their armor is strong enough to effectively withstand most small arms and melee weapons.

Officers and NCOs
Officers tend to have sidearms only, while NCOs tend to have their service rifles with them.

Rangers
Rangers have the most freedom when choosing weaponry. Most rangers use repeaters, trail carbines, brush guns, Sequoias, and other iconic ranger-esque weaponry while a few choose to remain with their service weapons or choose some other weapon they might prefer.

Bear Force
The NCR has a small force of vertibirds refurbished for executive use. Aaron Kimball appears in one of these. They also have a small force of supply and transport planes but likely no bombers or combat aircraft.

Motorized
The NCR has motorized divisions on the way to the Mojave as of the end of Lonesome Road but little else is known about them.

Heavy Troopers
These troopers use T-45 power armor units, stripped of their servos so that special training was not required to use them. Meant to be used as an advancing force should the need arise, the armor can take a beating and is especially effective against Legionnaires, who tend not to use armor-piercing weaponry.
