The Royal Marines have seen action in a number of wars, often fighting beside the British Army; including in the Seven Years' War, the Napoleonic Wars, the Crimean War, World War I and World War II. In recent times, the Corps has been deployed in expeditionary warfare roles, such as the Falklands War, the Gulf War, the Bosnian War, the Kosovo War, the Sierra Leone Civil War, the Iraq War and the War in Afghanistan. The Royal Marines have international ties with allied marine forces, particularly the United States Marine Corps and the Netherlands Marine Corps/Korps Mariniers.
