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. In 2004 the Unit returned to Iraq as part of a multi-national division peace-support operation. The commandos returned in April 2008 from a tour in the Helmand Province of Afghanistan as part of Operation Herrick. During the tour L-Cpl Matthew Croucher was awarded the George Cross for his action of jumping on a live grenade during a patrol. 40 Cdo returned to Afghanistan in 2010 for Op Herrick 12. They were the last British troops to leave Sangin, described as the "deadliest place in Afghanistan", after command was handed over to the US Armed Forces. A Company deployed with the UK Response Force Task Group in April 2011. Additional follow up forces were on board RFA Cardigan Bay. They then completed Exercise Red Alligator in October 2013: this trained their skills for the role of the Lead Commando Group. In the autumn of 2017, the Unit spearheaded the UK Military's crisis response (Operation RUMAN) in the Caribbean following the catastrophic damage caused to UK Overseas Territories by record-breaking Atlantic Hurricanes. 40 Commando deployed hundreds of troops to the British Virgin Islands, the Turks and Caicos Islands and Anguilla. Their efforts helped to reassure the affected communities, restore security, fix critical infrastructure and distribute humanitarian aid. 40 Commando are CBRN defense experts, expecting to be the lead unit in the event of a CBRN incident. In 2018 they participated in the annual chemical warfare exercise, Exercise TOXIC DAGGER, on Salisbury Plain involving over 300 military personnel, along with the RAF Regiment, the Royal Marines Band Service for casualty treatment and utilising Defence CBRN Centre expertise.
