Military Formations

Military Units and Formations

The following is a quick rundown of military organization. For details and links to more specific pages, please look at the Wikipedia article here (opens in new page).

In Atlantic America, there are a number of variations on this list. For example, the Kingdom of North Mississippi does not use Regiments, while the Kingdom of Michigan does not use Brigades. The Kingdom of Ohio uses the common hierarchy, even for artillery and cavalry units (see below).

Most nations do not have Army Group of Theater level commands, the exception being the Imperial Commonwealth.

Army – Common Hierarchy

Name Typical Commander Number of soldiers
Theater General, Field Marshal
Army Group General, Field Marshal Hundreds of thousands, or more
Army General/Lieutenant General 50,000 – 120,000
Corps Lieutenant General/Major General 12,000 – 36,000
Division Major General/Brigadier General 5,000 – 15,000
Brigade Brigadier General/Colonel 1,200 – 6,000
Regiment Colonel/Lieutenant Colonel 800 – 3,600
Battalion Lieutenant Colonel / Major 400 – 1,200
Company Captain / First Lieutenant 80 – 200
Platoon First or Second Lieutenant 30 – 60
Squad Sergeant (of some rate) 10
Team Sergeant 5



Artillery Battalions are divided into Batteries, and Batteries into Sections.


Cavalry Regiments are divided into Squadrons, and Squadrons into Troops.

Naval Hierarchy

Naval organization can change depending on the technology level, number of ships, and geographic area the navy is required to operate in. Levels will be taken in and out as necessary.

Example: The Navy of the Royal Kingdom of Quebec has three named fleets: the Lakes Fleet, Atlantic Fleet, and Arctic Fleet. Each of the Great Lakes has its own squadron, made of miscellaneous ships, while the Atlantic fleet has several task forces, with squadrons of like ships.

Name Commander
Fleet Fleet Admiral or Admiral All vessels in an ocean or navy
Numbered or Named Fleet Admiral or Vice Admiral All ships within a large geographical area
Task Force Vice Admiral A collection of ships of all types
Task Group Vice Admiral or Rear Admiral A collection of ships of similar types
Squadron or Flotilla Rear Admiral or Commodore Either a group of ships of the same type, or all ships operating within a specific geographical area
Division Commodore or Captain A group of ships of the same type
Ship Commander or Captain An individual ship


Air Force Hierarchy

The Air Force hierarchy is much more varied than the army or navy.  Most nations don’t have enough air craft to use every level of this hierarchy, and which levels are missing varies from one nation to another. In some cases, the Air Force is not an independent formation.

Size Aircraft Personnel
Air Command / Air Army
Numbered Air Force / Air Division 100+
Wing / Group / Air Brigade 48-100 1000-5000
Group / Wing / Air Regiment 24-48 300-1000
Squadron 8-24 100-300
Flight 4-6 20-100
Section 2 5-20
