1. COMMAND BRIEF I MARINE EXPEDITIONARY FORCE
Welcome.
We have two briefs for you today that we hope will give you an idea of what I MEF does for the Marine Corps and our Nation
First I will give you some background on the Command and then discuss the current operations that I MEF units are conducting.
Next, Col Obsorn will brief you on what his Marine Air Ground Task Force did recently
“READY AND RESPONSIVE”

2. CRITICAL ASSET Perverse enthusiasm for adapting and improvising
Ready to deploy
A Spartan attitude
Mentally agile
Marines will be prepared to “live hard” in uncertain, chaotic, and austere environments. We will strike a balance between being heavy enough to sustain expeditionary warfare and light enough to facilitate rapid deployment. We expect inhospitable conditions and train accordingly.
The Expeditionary Mindset
Expeditionary is an ethos that influences every aspect of organization, training, and equipment
A perverse enthusiasm for adapting and improvising.
“Come as you are” attitudes.
Understanding that you are going to deploy – you must be mentally and physically ready.
A Spartan attitude; an expectation and willingness to endure (with pride) hardship and austere conditions.
Constantly prepared to adapt to new situations and mentally agile enough to create innovative solutions to unanticipated circumstances.
Ever ready, self-sustaining, ready to fight when leaving the pier – this drives culture, mindset, thinking and equipment.

3. USMC ENDURING PRINCIPLES
Every Marine a Rifleman
Expeditionary Naval Force
Combined Arms Organization
Ready & Forward Deployed
Agile and Adaptable
Marines Take Care of Their Own
Enduring principles. Principles define fundamental beliefs that form the foundation from which Marines derive their ethos and basic operating instincts. The following principles help to further define the cultural identity of Marines in the most basic terms – they express WHAT WE BELIEVE. Vision and Strategy page 7

The forces listed make up the bulk of the extensive combat power of the MEF. These forces have the ability to operate across the spectrum of combat… from engagement through small scale contingencies to major theater war.
Any time I MEF conducts military operations, we deploy with reserve forces.

9. How we organize to fight
Marine Air-Ground Task Force
Scalable - based on the mission.
Not a unit; it is an organizational construct
Command Element (CE)
Ground Combat Element (GCE)
Aviation Combat Element (ACE)
Logistics Combat Element (LCE)
This is a graphic of the MAGTF
What distinguishes us…under one commander, unity of command and each subordinate commander understands who he works for. There is no convoluted or questionable chain of command. One commander. One purpose. One unified effort.
EFFECTIVE and Flexible. The MAGTF is organized for the mission. The MAGTF is not a unit. There is no 1st MAGTF. MAGTF is an organizational (some would argue theoretical) construct that we use to develop the appropriate force. Under one commander, he is able to prioritize the efforts of the ground combat element, the aviation combat element and the combat service support element. There is no competing priorities.
This unity of command principles is prevalent throughout our organization. For example,
GCE: BLT example - we take a rifle battalion and give it tanks, arty, recon, tracks; AT THE BATTALION LEVEL
ACE: We take a HMM and give it AV-8B’s, HMLA, and 53E’s. AT THE SQADRON LEVEL
No other service does this.
How is this different? The army has helicopters but they are either their own maneuver commander or they are in support of the ground element not reporting to. They have division but they are specialized in their training. The Air Force can do close air support, but their primary focus is to attack strategic targets. The Navy exemplifies unity of command to many – one ship, one commander; master and commander mentality. But the ship and the crew can not be task organized – they are designed and trained for a specific purpose.
We are America’s 911 force. This organizational construct, underpinned by a powerful institutional ethos and esprit de corps, enables the Marine Corps to fulfill its Title 10 responsibilities to be “the most ready when the nation is least ready.” The MAGTF construct allows us to accomplish this legislated, by law, responsibility to the nation and our citizens.
