Ratzel,

You might be attempting to reinvent the wheel. A Marine Expeditionary Unit (MEU) seems to have all the elements you listed plus air assets too.

Marine Expeditionary Unit
The smallest type of MAGTF is the Marine Expeditionary Unit (MEU) (Special Operations Capable) (SOC). The command element is the standing headquarters for the MEU, usually headed by a colonel. The ground combat element is a battalion landing team (BLT), which is composed of an infantry battalion reinforced with tanks, artillery, engineers, amphibious vehicles, light armored vehicles, and other ground combat assets. The air combat element is composed of a composite squadron of fixed and rotary-wing aircraft and an Air Traffic Control (ATC) and command and control detachment. The combat service support element consists of a Combat Logistics Battalion (CLB) which handles the logistics and administration needs of the MEU. The specific makeup of the MEU can be customized based upon the task at hand; additional artillery, armor, or air units can be attached, including squadrons of F/A-18 Hornet and Harrier jets.

There are usually three MEUs assigned to each of the U.S. Navy Atlantic and Pacific Fleets, with another MEU based on Okinawa. While one MEU is on deployment, one MEU is training to deploy and one is standing down, resting its Marines, and refitting. Each MEU is rated as capable of performing special operations.

This post comes late to the discussion, but considering the activities of a MEU over the past year in Afganistan and the
results in Helmand Prov. the combined arms force seems to fit the basic description minus airborne and ranger school.

It is half the size of the unit envisioned by you, but covers a lot more options with less troops. The Marines have been fleshing out Battalion Landing Teams with assets needs for specific missions since the mid 1950's.

Todays MEU's grew out of that mix and into what is operational today.
