Combined Operations

Combined Operations denote coordinated military campaigns conducted by forces from multiple services or armed formations to achieve a unified objective. Originating in pre-modern expeditionary warfare and codified through 19th–21st century practice, they integrate naval, land, and air elements under unified planning and command to exploit strategic, operational, and tactical advantages.

Definition and Principles

Combined Operations are defined by integration of distinct armed services—naval, land, air, and often special forces—into a single synchronized effort. Key principles include unity of command, concentration of force, surprise, economy of effort, and interoperability among Royal Navy, United States Navy, Soviet Navy, Imperial Japanese Navy elements and their corresponding army and air service counterparts such as the British Army, United States Army, Red Army, Imperial Japanese Army, Royal Air Force, and United States Air Force. Command arrangements draw on doctrines exemplified by the Gold Plan, the Anaconda Plan, and concepts tested at the Siege of Sevastopol (1854–1855), Gallipoli Campaign, and D-Day. Combined Operations rely on joint staff structures like combined task forces, combined joint task forces, and multinational coalition staffs used in NATO operations and United Nations peace enforcement.

Historical Development

Early antecedents appear in amphibious expeditions by the Athenian Navy and Alexander the Great's coordination of siegecraft and fleet action. Medieval and early modern examples include campaigns by the Spanish Armada and operations during the Anglo-Spanish War (1585–1604). Industrial-era development accelerated with steam navies and rail logistics during the Crimean War, culminating in large-scale 20th-century practice during World War I and World War II. World War II campaigns—such as the Allied invasion of Normandy (Operation Overlord), the Battle of Midway, and the Burma Campaign—crystallized modern combined doctrine. Cold War crises like the Cuban Missile Crisis and interventions in Korea, Vietnam War, and the Falklands War further refined joint command, while post–Cold War operations in Iraq War, War in Afghanistan (2001–2021), and Operation Restore Hope showcased multinational coalition models.

Organization and Command Structures

Command structures vary from single-service expeditionary commands to integrated joint commands. Models include theater-level commands such as Supreme Headquarters Allied Expeditionary Force, theater armies like United States Central Command, and combined maritime task forces like Combined Task Force 151. Leadership conventions use combined or joint chiefs, deputy commanders from partner services, and liaison officers drawn from formations like the Royal Marines, United States Marine Corps, SAS (Special Air Service), GURKHA regiments, and United States Navy SEALs. Legal frameworks underpinning multinational command derive from treaties such as the North Atlantic Treaty, status-of-forces agreements used in Bosnia and Herzegovina, and coalition accords negotiated for Operation Desert Storm.

Operational Roles and Tactics

Combined Operations span amphibious assaults, air-land campaigns, maritime interdiction, riverine warfare, urban operations, and special operations. Tactics integrate carrier aviation from USS Enterprise (CVN-65) and HMS Illustrious with airborne forces like the 101st Airborne Division and British Parachute Regiment, and mechanized elements exemplified by 7th Armoured Division and U.S. Marine Expeditionary Units. Key methods include joint fires coordination seen at Kursk, vertical envelopment demonstrated during Operation Market Garden, littoral maneuver during the Baltic Sea campaigns, and logistics-enabled operational reach as in the Berlin Airlift.

Notable Combined Operations and Campaigns

Prominent examples include the Invasion of Normandy (Operation Overlord), the Allied invasion of Sicily (Operation Husky), Battle of the Atlantic, Battle of Midway, the Dieppe Raid, the Guadalcanal Campaign, the Dardanelles Campaign (Gallipoli), Operation Torch, Operation Market Garden, the Falklands War (1982), Operation Desert Storm (1991), Operation Enduring Freedom (2001), and Operation Iraqi Freedom (2003). Each case demonstrates different emphases: amphibious doctrine at Dieppe Raid, carrier-centric attrition at Battle of Midway, and combined land-air-sea logistics at Operation Overlord.

Training, Doctrine, and Interoperability

Professional education and joint training institutions—Royal Navy School of Amphibious Warfare, U.S. Naval War College, NATO Defence College, and service staff colleges such as Staff College, Camberley—codify doctrine like the Jointery concepts and manuals from Joint Chiefs of Staff and Ministry of Defence (United Kingdom). Interoperability standards are implemented through exercises such as Exercise Trident Juncture, RIMPAC, Operation Bright Star, and multinational readiness trials conducted by NATO Response Force. Language training, common communications protocols (Link systems used by NATO), and shared logistics frameworks mitigate friction among units like French Foreign Legion contingents, Royal Australian Navy task groups, and German Bundeswehr formations.

Technological and Logistical Support

Technology underpins combined effects: aircraft carriers, amphibious assault ships (LHD/LHA), amphibious vehicles like the Landing Vehicle Tracked, precision munitions such as the Tomahawk (cruise missile), airborne command and control platforms like E-3 Sentry, and satellite communications. Logistics systems incorporate sealift from Military Sealift Command, prepositioned stocks exemplified by Prepositioning Program, and strategic airlift via C-17 Globemaster III and C-5 Galaxy. Maintenance, medical evacuation (MEDEVAC), and joint supply chains are coordinated through agencies like NATO Logistics Command and theater sustainment commands used in Operation Iraqi Freedom.
