What is an Amphibious Operation?What is an Amphibious Operation?

“An amphibious operation is a military operation launched from the sea by an amphibious force, embarked in ships or craft with the primary purpose of introducing a landing force (LF) ashore to accomplish the assigned mission.”

- Joint Publication 3-02

Strengths and Capabilities Strengths and Capabilities of Amphibious Warfareof Amphibious Warfare

• Strategic mobility and flexibility

• Strike at a point of choosing

• Projection of power ashore

• Forcible entry

Limitations Limitations of Amphibious Warfareof Amphibious Warfare

• Initially vulnerable

• Natural Hazards– Environmental Conditions

• Sea• Terrain• Climate

• Complexity

Themes of Amphibious Themes of Amphibious OperationsOperations

Problems of the TadpoleProblems of the Tadpole• Limited and temporary ability

for:– a naval force to project

influence over land.– a ground force to project

influence over the sea.

• Transformation– Vulnerable time for the landing

force– Reduce vulnerability with a

rapid build up of combat power ashore.

The landing itself is rarely the The landing itself is rarely the key problemkey problem

• Most attackers have succeeded getting ashore.

• Defenders are rarely able to cover an entire shoreline

• Objective of amphibious planners to choose a landing site of minimal resistance.

The problems of commandThe problems of command

• Amphibious Operations incorporate:– Naval Warfare, with– Land Warfare

• The complexity of each type of warfare today necessitates a separate commander for each.– Commander Amphibious

Task Force (CATF)– Commander Landing Force

(CLF)

The amphibious invasion is a means The amphibious invasion is a means to an end, not an end to itselfto an end, not an end to itself

• The landing is a prerequisite for accomplishing a subsequent ground mission.

• The ground mission should drive the amphibious planning (not vice versa).– Historical examples of planners becoming so

concerned with getting ashore, that they give little or no thought to what to do when they got there.

– Roanoke Island in 1862 and Fort Fisher in 1864

The influence of terrain and geographyThe influence of terrain and geography• Only certain portions of the

world’s coastlines are assailable by amphibious forces.– Dictates if and where a

landing can be made– Influences the attacker’s &

defender’s plans

• Has spurred the development of some specialized amphibious equipment

The amphibious operation as a The amphibious operation as a form of envelopmentform of envelopment

• Maneuver– Turning the enemy’s flank by sea to gain an

advantageous position.

• Flexibility– “Amphibious flexibility is the greatest strategic asset

that a sea power possesses.” -B.H. Liddell, Marines and Strategy,

p. 31

• Strategic Envelopment (i.e. Gallipoli)• Operational Envelopment (i.e. Inchon)

The inherent chaotic and decentralized nature of The inherent chaotic and decentralized nature of landingslandings

• Amphibious Operations by nature:– Have many moving parts– Have inherent friction– Are a small unit action

• Direct control limited to each landing craft

• Small unit leadership and initiative are imperative to success.

• Higher level commanders can’t assume control of the land fight until landing forces begin to organize ashore.

The development of amphibious The development of amphibious technology and techniquestechnology and techniques

• Amphibious operations are specialized and complex.

• Requires specialized amphibious:– Equipment

• Vehicles, landing craft, defensive obstacles

– Tactics and Techniques• Naval Gun Fire Support

Amphibious AssaultAmphibious Assault“…an attack launched from the sea by naval and

landing forces embarked in ships or craft involving a landing on a hostile shore”

- Joint Publication 1-02• Purpose

– Prosecute further combat operations– Obtain a site for an advance naval or air base– Deny the use of an area or facility to the enemy.– Fix enemy forces or attention.

• May be an opposed or unopposed landing

Amphibious DemonstrationAmphibious Demonstration

• Deceive the enemy with a show of force

• A form of deception

• Cause the enemy to react or commit forces without actually landing

• Example: 4th MEB in Desert Storm

Amphibious WithdrawalAmphibious Withdrawal

• Withdraw forces from a hostile shore for tactical or operational reasons.

• May be an opposed or unopposed withdrawal.

• Example: Inchon

Amphibious RaidAmphibious Raid

• An amphibious assault with a planned withdrawal

• Typically short in duration with the intent on inflicting damage, securing information/intelligence, creating a diversion, or capturing/rescuing individuals or materials.

• Example: MEU(SOC)

Other Amphibious OperationsOther Amphibious Operations

• Using the capabilities of an amphibious force for military operations other than war (MOOTW)– Non-combatant Evacuation Operations (NEO)– Foreign Humanitarian Assistance (FHA)
