In March 2003 a coalition force, under the overall command of the United States, entered Iraq. During Operation TELIC 1, the liberation of Iraq, on the night of 20 March 2003, 40 Commando RM, under the command of Lt Col G K Messenger DSO OBE, mounted an amphibious helicopter assault to seize key Iraqi oil infrastructure on the Al-Faw Peninsula. As the first conventional troops on the ground, the strategic significance of the operation was immense and, as the Divisional Main Effort, the assault was supported by a vast array of coalition firepower. The Commando Group's role in the success of the coalition operation in Iraq was pivotal and profound. In a two-week period of intense operations, it secured key oil infrastructure, cleared a large expanse of enemy held terrain, and defeated a major enemy stronghold on the periphery of Basra, killing over 150 Iraqi soldiers and taking 440 prisoners.
