Royal Marines conflict World War II
The Corps of Royal Marines (RM), also known as the   Royal Marines Commandos, are the United Kingdom's special operations capable commando force, amphibious light infantry, and also one of the five fighting arms of the Royal Navy. The Royal Marines trace their origins back to the formation of the "Duke of York and Albany's maritime regiment of Foot" on 28 October 1664, and can trace their commando origins to the 3rd Special Service Brigade, now known as 3 Commando Brigade, which was formed on 14 February 1942, during the Second World War. The Corps also provides the Naval Musicians. 
As a specialised and adaptable light infantry and commando force, Royal Marine Commandos are trained for rapid deployment worldwide and capable of dealing with a wide range of threats. The Royal Marines are organised into 3 Commando Brigade and a number of separate units, including 47 Commando (Raiding Group) Royal Marines, a company-strength commitment to the Special Forces Support Group and the Royal Marines Band Service. The Corps operates in all environments and climates, though particular expertise and training is spent on raiding, amphibious warfare, arctic warfare, mountain warfare, expeditionary warfare, and its commitment to the UK's rapid reaction forces.
Throughout their history, the Royal Marines have seen action in a number of major wars – including the Seven Years' War, the Napoleonic Wars, the Crimean War, World War I and World War II. The Corps has been largely deployed in expeditionary warfare roles in conflicts 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 Corps has close international ties with allied marine forces, particularly the United States Marine Corps and the Netherlands Marine Corps (Dutch: Korps Mariniers).
