New California Republic Army The New California Republic Army is the standing land - based military force of the New California Republic , and is one of the largest known armed forces in the post - War United States . Background . The origins of the NCR Army are not detailed , however , by 2241 it was the largest standing force in New California composed of several divisions . Some amount of time after the Destruction of Control Station ENCLAVE , an early major engagement of the NCR Army took place during the NCR - Enclave conflict , where the NCR , alongside the Brotherhood of Steel , overran and annihilated the Enclave ' s last known holding in New California . While the casualties on the NCR ' s side were tremendous , the Brotherhood of Steel finished off the remaining Enclave soldiers stationed there , with only a few managing to escape into the wastes . The NCR Army has continued to grow and serve the NCR ' s interests , securing its expansion and protecting territories under its control . It has distinguished itself both in its near destruction of various raider tribes such as the Vipers , the Jackals and the Khans and proved quite resilient in the war against the Brotherhood of Steel . By 2281 they were the largest armed forces in the entire Mojave Wasteland , rivaled only by Caesar ' s Legion , who were gathering their forces for another attack on Hoover Dam . The Republic protected Hoover Dam and other outlying territories falling under the limited jurisdiction they possess in the Mojave Wasteland , though the stalemate with the Legion forced them to stretch their forces far and thin along the Colorado River . This resulted in the loss of Camp Searchlight and Nelson to frumentarii attacks . Organization . The military ' s organization is inspired by the pre - War American structure , although adapted to the much smaller population of the wastelands . The standard level of organization of infantry forces is the battalion , which in turn is divided into companies under the command of a Captain . Companies are in turn divided up into platoons , for example Lieutenant Hayes in Primm is in charge of a platoon which belong to the 1st Company , 5th Battalion . These are sometimes divided into squads ( created at the Commanding Officer ' s discretion ) and are typically led by a sergeant or other non - commissioned officer , for example Sergeant Lee , who commands the strike force sent to retake the NCR Correctional Facility from the Powder Gangers . Other branches in the military separate from the regular army include NCR Recon ( which includes 1st Recon ) , the NCR Heavy Infantry Corps which are under direct command of General Lee Oliver , medical corps , logistics corps ( quartermasters are typically non - commissioned officers ) and the NCR military police . Military bases of the army , typically called " camps " , are always under the command of a commissioned officer ( usually a major e . g . Polatli or ) . The larger camps that train recruits , such as Camp McCarran , will also have Drill Sergeants . The Chief of Staff is the highest - ranking member of the army , serving as its commander . In 2281 , the Army Chief of Staff is General Lee Oliver . Rank Structure . The NCR Army utilizes a structure of rank that is based off the old United States Army . Members of the army are divided into commissioned officers and enlisted . Enlisted members with leadership authority are called non - commissioned officers . Known ranks of the NCR Army are : Commissioned Officers Enlisted Basic Training . The NCR Army of 2281 features a basic training regimen , consisting of a two - to - three week series of abbreviated tutelage on weapons familiarity and explosive ordnance handling , along with intense physical conditioning . The reason for this short training period is to produce field - ready troops as soon as possible , to meet the fitted needs for personnel size based on their mission , especially with the where there are high casualties and troops are killed daily . Drill Sergeants run the basic training courses at various bases , such as Camp McCarran . Branches . The New California Republic ' s military is large and diverse , composed of several dedicated branches , the largest of which is the infantry . Infantry Corps . The bulk of the infantry is composed of troopers , a mixture of trained volunteers and conscripts that are employed in offensive and defensive missions . The majority of troopers seen in the Mojave are infantry , and every trooper receives basic infantry training regardless of their specialty in the army . The infantry is the first and last line of defense and offense for the army , and its members are expected to go into action regularly against any and all enemies of the NCR , ranging from Fiends to Caesar ' s Legion . The numerous mutated beasts of the wasteland are no less hostile , so army infantry must be equally ready to fight them as well . The regular infantry composes the majority of the army ' s combat strength , but the Heavy Infantry Corps and the Rangers add to that significantly , offering heavy infantry and elite light infantry / special forces capabilities to NCR Army commanders . The Infantry Corps also includes specialized units like 1st Recon , formally 1st Reconnaissance Battalion , an elite sniper unit that goes by the motto " The Last Thing You Never See . " Heavy Infantry Corps . The Heavy Infantry Corps are much better trained and equipped than the standard troopers , serving directly under the personal command of General Lee Oliver . They are equipped with NCR salvaged power armor , suits of scavenged T - 45d power armor with the servos and pistons removed , which the NCR gained from their war with the Brotherhood of Steel , giving them superior protection than the standard soldiers . They carry heavy weaponry , such as the high - capacity light machine guns , and occasionally . Rangers . A separate special forces branch , known as the NCR Rangers , became a part of the NCR Army in 2271 . The Desert Rangers signed the Ranger Unification Treaty with the NCR at the Mojave Outpost , in which they agreed to become part of the NCR military in exchange for protection of Hoover Dam and Nevada from Caesar ' s Legion . Most Rangers wear NCR - designed Ranger patrol armor , while veterans opt for the so - called Black armor : a traditional Desert Ranger trenchcoat worn together with a pre - War riot armor and helmet . Rangers have access to superior weapons , such as trail carbine s , anti - materiel rifle s and brush gun s . These weapons have a slower rate of fire than the standard service rifle , but they also possess greater stopping power per round . The Rangers perform a variety of specialized tasks , handling things that are too difficult or outside of the regular army ' s role . They are trained to be ready for anything and everything , and are both the army ' s special forces and its shock troops . Even Caesar ' s Legion holds respect for the Rangers , with common Legionnairies calling them " the best the Profligates have to offer . " One special role of the Rangers is the NCR Ranger hit squad , a small force of Rangers tasked with eliminating individuals who have become especially dangerous enemies of the NCR . A difference between Rangers and the rest of the army is they do not use the standard army rank structure . There are no privates , sergeants , lieutenants , colonels or generals in the Rangers . The only rank that exists is ranger . The only exception to this is the chief , who serves as the commander of the Rangers . In 2281 , the Rangers were led by Chief Hanlon . Air Force . Responsible for all aviation operations within the NCR Army , the Air Force is one of the army ' s smallest branches . The NCR has very limited airpower ; its small fleet of captured Vertibird s is strictly reserved for political or military VIPs . Out of those Vertibirds , at least one Vertibird named " Bear Force One " serves the President of the New California Republic ' s personal transport . Logistics Corps . Responsible for supply , ordnance and transportation operations , the Logistics Corps supports the entire NCR Army . It is responsible for the acquisition , maintenance and distribution of all manner of supplies within the army , and has even obtained and begun to use motorized vehicles . However , the exact number and the type of vehicles is unknown . It is known that the Logistics Corps possesses a number of scavenged US Army truck s , which can be used for moving troops , equipment and supplies . These are kept running by a dedicated team of mechanics and well - stocked workshops , such as the truck repair depot at Camp McCarran . Robots . The NCR Army has at least one functional which is stationed at Hoover Dam . Military Police Corps . The NCR Army has a dedicated law enforcement corps . The Military Police enforce military law on all NCR Army posts , and are responsible for watching their fellow troopers as much as the base perimeter . MPs can be seen on duty at Camp Forlorn Hope and at Camp McCarran . The Military Police , under the leadership of Captain Marie Pappas , also pull duty on the New Vegas Strip , keeping regular NCR Army troopers in line when they come to the Strip on leave . This duty is complicated by Mr . House ' s securitrons , whom the MPs are forced to work alongside as part of an uneasy peace with House . The MPs on the Strip are mandated by treaty to use non - lethal weapons only , but Captain Pappas can openly carry a firearm as the MP in command . Lastly , the Military Police provide security for the NCR Embassy and all of its personnel , namely Ambassador Dennis Crocker . Relations with the outside . The NCR Army is not intended to fulfill any role other than a military one . Matters of diplomacy are left to be decided by the civilian branch of the government , such as the president , the congress and foreign ambassadors like Dennis Crocker . Nonetheless , army troopers and officers sometimes find themselves forced into being soldiers and law enforcement officers in the Mojave , where civilian law and order is next to nonexistent and a faction ' s rules extend as far as the range of its guns . Some , like Colonel James Hsu , handle these complications about as smoothly as is possible , but others , like Colonel Cassandra Moore , stick completely to soldiering and refuse to play cop or peacekeeper . The NCR Army has a widely varied reputation in the Mojave in 2281 . Whether it is looked upon as an evil or benign organization , or anything in between , depends greatly on what affiliations a person has . Groups that are considered enemies of the NCR , such as Caesar ' s Legion , the Great Khans , Brotherhood of Steel and the Fiends are all openly hostile towards NCR military personnel , and frequently clash in violent battles . Due to their mutual hatred for the NCR , Caesar ' s Legion sent an to the Great Khans on the pretext of forming an alliance to fight them by absorbing the Khans into the Legion . Some small bands of settlers are antagonistic towards the NCR Army ( and the NCR as a whole ) because of feelings of unwanted imperialism or complaints of poor quality of governance . Bandits and raiders are hostile to the army because they want to do whatever they please , to whomever they please , something the army is not willing to allow . Weapons and Equipment . As large as the NCR Army is and as much as it is expected to do , the army has found it practical to utilize mass - produced equipment made from durable materials that perform reliably and can survive harsh treatment . The NCR Army is visibly different from other armed groups in the wastelands of the former United States , possessing a remarkably standardized line of equipment and weapons . The army ' s standard infantry weapon is the semi - automatic service rifle , but troopers can also be equipped with , varmint rifle s or caravan shotgun s when there are shortages . Specialized units like the 1st Reconnaissance specifically choose the hunting rifle over the service rifle because of the former ' s greater effective range and more potent . The is the standard sidearm of all members of the NCR Army . All of these weapons are provided by the , who handle a majority of the weapons contracts of the army . Uniforms for troopers is standardized NCR armor , supplied by the Crimson Caravan Company . It consists of a reinforced leather breastplate on the torso and upper back , supported by leather shoulder pads worn over brown fatigues . Despite the modest training and equipment the troopers receive , it is superior to equipment employed by most adversaries of the NCR , namely raiders , nomadic tribes or the numerous recruit legionaries of Caesar , who are rarely sent into battle wielding more than a mere or crude pistols . The NCR possess various pre - War weapons and equipment as well . Hoover Dam is protected by an anti - aircraft gun capable of firing flak shells to bring down aircraft . After the NCR gained control of the HELIOS One facility by forcefully taking it from the Brotherhood of Steel in , they had unknowingly gained possession of the Archimedes I and Archimedes II super - weapons .
