New Arlington

Military
The colonial government of New Arlington used the rising instability in the Outer Colonies as a cause for establishing a regular army, called the New Arlington Free Colonial Armed Forces, or NAFCAF for short.

Many members of the Colonial Congress believed the official reason for the regular military's established, but several insurrectionist-collaborators and sympathizers had a hidden agenda and wished to use the colony-loyal military to launch a rebellion against the UEG.

The NAFCAF played a large role in the New Arlington Rebellion but it was outmatched by the UNSC's forces and defeated, and then dismantled after the war.

Army
The regular army branch of the NAFCAF, the New Arlington Colonial Army, also known as the NACA, called for three regiments —two infantry regiments and an artillery regiment. Each regiment consisted of two battalions, and the artillery regiment had several M80A1 105mm howitzers each.

A separate scout and reconnaissance corps called the Rangers was set-up as a battalion.

Initially, the army did not include tanks when it was established, but in 2490, fifty-eight M808 light tanks were purchased and added to their vehicle fleet, and the Armored Cavalry Battalion was founded.

In addition to the regular army, there was a militia known as the Free Militia was established to act as a military reserve force, made up of irregular volunteers.

Air Force
The NACA was supported from the air by the New Arlington Colonial Air Force, or NACAF. The NACAF was in charge of providing their ground forces with air support and aerial reconnaissance. The Air Force was not responsible for air-based transportation of troops and personnel, which was left to their ground forces to handle via. The reasoning behind this was because the secessionists hoped that this would allow their air forces to focus on combating enemy air power and keeping the skies clear for their ground forces.

The core of their air fleet was composed of three squadrons of F/A-13 Razor fighters.
