A core component of the country's Rapid Deployment Force, the Corps's 3 Commando Brigade is capable of operating independently and is highly trained as a commando force. It is trained to deploy quickly and fight in any terrain. The Royal Marines have the longest basic infantry training course of any NATO combat troops.
3 Commando Brigade is a commando formation of the British Armed Forces and the main manoeuvre formation of the Royal Marines. Its personnel are predominantly Royal Marines, supported by units of Royal Engineers, Royal Artillery, The Rifles, and the Fleet Air Arm, together with other Commando Qualified Sailors, Soldiers and Airmen.
The brigade was formed in 1943, during the Second World War with a mixture of army commando and Royal Marine commando units and served in the Burma Campaign.
