5th RM Battalion

The 5th RM Battalion was originally raised for a brief period at the end of World War I (September 1918-February 1919), and was again raised on 2 April 1940 following mass mobilisation and the influx of "hostilities only" (HO) marines. The battalion was raised at Cowshot Camp in Brookwood (now part of the Pirbright Camp complex), being incorporated into 101 RM Bde, along with the 1st RM Battalion. Between August and October 1940 the battalion took part in operations in Dakar. On return until August 1943 the battalion conducted extensive training in Wales, Scotland, the Isle of Wight and Burley, where the battalion reformed as 45 RM Commando on 1 August 1943.^[2] It was commanded between March 1940 and February 1942 by Arnold Reading.^[3]

After reforming and retitling, the unit transitioned to the Commando role as a formed unit, by-passing the individual volunteer and selection process undertaken by Army Commando candidates. Personnel undertook, and completed, the Commando Basic Training Course at Achnacarry, Scotland. As part of the 1st Special Service Brigade, the Commando participated in Operation Overlord (the D-Day Normandy landings), before going on to move through Europe into Germany, including Brachterbeek on 23 January 1945.^[4] During the Ardennes Offensive, the retitled 1st Commando Brigade was given the task of holding a stretch of the River Meuse; it was during this period of operations that Lance Corporal H. Harden, a medical orderly of the RAMC attached to 45 (RM) Commando, won the Victoria Cross.^[5]

Post-World War II reorganisation

Following the Second World War both 1st Commando Brigade (Nos 3, 4 and 6 Army Commandos and 45 RM Commando) and 2nd Commando Brigade (Nos 2 and 9 Army Cdos and 40 and 43 RM Cdos) disbanded, leaving 3 Cdo Bde (then comprising 1 and 5 Army Cdos and 42 and 44 RM Cdos) in place in the Far East. 3 Cdo Bde reorganised, disbanding 1 and 5 Army Cdos, and took on 45 RM Cdo, which joined the Bde in Hong Kong, from the UK, in January 1946. In order to preserve the heritage of a 2 Cdo Bde unit, as well as that of 1 Cdo Bde (45 RM Cdo), 44 Commando was retitled 40 Commando (which had been disbanded in UK in October 1945) and took on 40 RM Cdo's colours, battle honours and traditions, albeit with 44 RM Cdo's manpower. The three remaining commandos were restyled 40, 42 and 45 Commandos RM in March 1946.^[6]

The Commando unit was based in Hong Kong between January 1946 and May 1947, conducting internal security duties, as part of 3 Cdo Bde RM. Between May 1947 and December 1948 the Commando moved to Malta, during which time it deployed to Libya, Palestine, Suez and Jordan. The Commando unit returned to Hong Kong in December 1948 and from there deployed to Malaya between 1950 and 1952 taking part in operations during the Emergency. Between 1952 and 1959 the Commando was once again based in Malta. In September 1955 45 Commando was deployed to Cyprus to undertake anti-terrorist operations against the EOKA guerrillas who were fighting against British control of the island. EOKA were a small, but powerful organisation of Greek Cypriots, who had great local support from the Greek community. The unit traveled to the Kyrenia mountain area of the island and in December 1955 launched Operation Foxhunter, an operation to destroy EOKA's main base.^[7]

Then in 1956 the unit deployed to Egypt as part of the response to the Suez Crisis, conducting the first helicopter assault in history.^[8]

1960s

Between 1960 and 1967 the Commando was based in Aden, from where it conducted 10 operational tours in the Radfan during the Aden Emergency. The Commando unit also deployed briefly to Kuwait following an Iraqi threat to her Independence in 1961. In January 1964, part of then Tanganyika, later to become the Tanzanian Army mutinied. 45 Commando who were in Aden boarded HMS Centaur and sailed to East Africa and anchored off-shore from Dar es Salaam. The revolt was put down after 45 Commando landed by helicopter at Colito Barracks with other operations around the country over the coming days. ^[9]

The last elements of the 45 Commando left Aden on 29 November 1967 to return to the UK for the first time since the end of World War II. They set up home in Stonehouse Barracks, Plymouth.^[10]

1970s/1980s

In 1970 the Commando began Arctic training for the first time, taking on the role of Britain's mountain and Arctic warfare experts (joined later by the other Commandos). 45 Cdo RM deployed to Norway for the first of many winters in 1971, which coincided with a move of the unit from Stonehouse, Plymouth to the old Naval Air Station, RNAS Arbroath (now RM Condor) in Arbroath, Scotland, where the unit still remains.^[11] This period in the unit's history is characterised by the alternation of Northern Ireland tours^[10] and winters in Norway, protecting NATO's northern flank.^[12]

In 1993 The Commando unit was deployed to Belize for the last operational jungle tour in that country. In a mirror image of its 1961 deployment to Kuwait, the Commando returned on Operation Driver in 1994, in support of Kuwait, following some threatening troop movements by the Iraqis on their side of the border. In 1998 the Commando unit was redirected from an exercise in Belize, to assist Nicaragua and Honduras following the devastation caused by Hurricane Mitch.^[14]

In January 2004 the unit deployed to Northern Ireland (Operation Banner) for 6 months in support of peacekeeping operations, returning home in June. On return, it became the Spearhead Lead Commando, a role assumed on a rotational basis. The Lead Commando is at a high level of readiness, able to deploy at short notice on operations worldwide.^[19]

In September 2004, whilst still Lead Commando unit, the Group deployed to the United States on Exercise BLACKHORSE. This was split into two phases, the first of which took place with the United States Marines Corps Ground-Air Combat Centre at 29 Palms, California. This 900 square miles of desert, allowed realistic live firing, involving artillery and air strikes. The second phase took place at the Marine Corps Mountain Warfare Training Centre, high in the Sierra Nevada Mountains. An early snowfall meant the Commando was able to carry out cold weather warfare training, operating between 7000 and 11,000 feet (3,400 m). 2006 saw the Unit deploy to Norway for further Arctic training which culminated with a NATO led exercise.^[20]

The focus switched to preparation for deploying to Afghanistan on Operation HERRICK 5 in late 2006. This deployment saw the Commando take on a number of different roles, the principal one being that of the Operational Mentoring and Liaison Team (OMLT). The OMLT task was to work alongside the Afghan National Army and develop it into a self-sufficient organisation. The Unit returned from Afghanistan in April 2007.^[21]

October 2008 saw the Commando unit return to Afghanistan as Northern Battle Group in Helmand Province on Operation HERRICK 9. The operational area of responsibility was the Upper Sangin Valley which extended for 80 km along the length of the Helmand River. The Battle Group was in excess of 1200 strong, half of whom came from 45 Commando.^[22]

April/May 2009 saw the return of the Commando to Arbroath in Scotland for reorganisation ahead of a winter deployment to Norway to practice cold weather and amphibious tactics.^[18]

It became clear in 2018 that 45 Commando would, as would 40 Commando, form the infantry component of a Littoral Response Group, as part of restructuring in the Future Commando Force programme.^[29]

2020s
