The New California Republic (NCR) is a democratic federation based in California, with holdings in Nevada, Oregon, Mexico and along the Colorado River. The Republic is dedicated to the old world values, such as democracy, liberty and the rule of law. The NCR also strives to restore order and progress in the Wasteland, though in recent years, it has faced difficulty living up to those standards.
The New California Republic was born from the remnants of the survivors of Vault 15 and the small walled-in community they founded known as Shady Sands. n 2186, the town of Shady Sands changed its name to the "New California Republic" and formed a trial council government to draft a constitution. Four more settlements joined the council, and in 2189 the NCR was voted into existence as a sprawling federation of five provinces: Shady Sands, Los Angeles, Maxson, Hub, and Dayglow.
The NCR's military is composed of several Divisions, including special cavalry and mechanized units. In addition, many of their major cities are protected and patrolled by heavily armed police officers. One of their Special Forces units consists of the New California Rangers, a select group that is pledged to protect the people of the Wastes much like the Texas Rangers of old. The Rangers are said to have numerous safehouses throughout the wastes, and they use these to strike at slavers outside of NCR territory (usually in the North).
The rangers are recruited from the best of the NCR military and even then, 80% do not finish training and drop out. Those that finish and are awarded the badge have proven that they are "quieter than a shadow and deadlier than even a deathclaw."
In order to fulfill their objectives, they employ high end equipment (combat armor, various assault rifles, heavy weapons and even vehicles), numerous safe-houses in the wastes and unorthodox tactics. Their regular patrol armor is hand-made in the NCR, while the elite black armor comes from pre-War LAPD design. Ranger combat helmets are old Pre-War gear that have built in low-light optics, allowing for more advance night scouting and sharpshooting to assist the troopers. Their superior training, superior weaponry and assortment of pre-war and post-war technology allows them to tip battles in NCR's favor even when a situation may see them outnumbered and outgunned. Rangers can also operate as spies and conduct police work. (From The Vault)
