Die Jakkalsgat: US mechanised infantry battalion structure

A Little Help:

A primer on US mechanized infantry unit structure, for those of my readers who felt stung by the recent piece citing Mr. Drum. The comments section is as useful as the piece itself for starting to get a handle on how the US Army's fighting units are structed, and how they operate.

Once you've got that down, you have to realize that the Marine Corps operates on a different principle entirely. The 'organic unit' for the USMC is the Marine Air/Ground Task Force (MAGTF), which handles the combined arms aspect in the way that TF 2/7 does, but the barracks 2/7 does not. However, Marines also have battalions, which is what 3/5 means below: 3rd Battalion, 5th Marines. MAGTFs, though the organic unit for fighting and organization purposes, don't carry the unit's history. This has the result that Marines think of themselves as part of this or that battalion, though much less so than in the Army: Marines think of themselves first and last as Marines, not as cavalry, or 7th Cav, or 101st Airborne.

MAGTFs come in several sizes. The largest is normally the Marine Expeditionary Force (MEF), and the smallest the Marine Expeditionary Unit (MEU). There are also sometimes special MAGTF that are created for a particular function: Task Force Tarawa, for example.

The use of combined arms and joint force combat has been stunningly successful in Fallujah. Not only are these Army task forces working well together, they're combining well with the Iraqi National Guard, and the Marines, and the air assets that are tasked with supporting them. The lack of friendly fire casualties under these circumstances is astonishing.

In addition to not having called down fire on allied positions, the Coalition forces apparently have not failed to call down fire on enemy positions. It was just such a failure to fire -- having misidentified massing Confederate infantry as a support unit -- that caused the Union army to lose the first battle of Manassas, a.k.a. the first battle of Bull Run. Even amid all the confusion of units in Fallujah, fire support has been outstanding by all accounts.
