NATO, as an organization, did not participate in the military operation of the U.S.-led multinational coalition forces in Iraq. The Alliance’s role in Iraq was limited to training Iraqi military personnel. In doing so, NATO supported the Iraqi government to build an effective armed force and enhance its defence capabilities. On 22 June 2004, the Prime Minister of the Transitional Government of Iraq requested the Secretary General of NATO to provide assistance for the training of Iraqi military personnel and for resolving other technical issues. On 28 June 2004, At the NATO Summit in Istanbul, NATO Heads of State and Government agree to assist Iraq with training of its security forces. On 30 July  of the same year, NATO Training Implementation Mission was established in Iraq. On 7 August 2004, NATO Mission Iraq undertook to train Iraqi military personnel both inside the country and in the territory of NATO member states. Initially, the Training Implementation Mission included 50 officers. On 22 September 2004, based on its recommendations, the North Atlantic Council decided to increase the personnel of the Mission and establish Iraqi Training, Education and Doctrine Center. The number of personnel serving in the Mission increased to three hundred and they were assigned to train middle and high-rank Iraqi military personnel. The Mission was renamed NATO Training Mission in Iraq (NTM-I) – a non-combat capacity-building mission aimed at training, equipping and providing technical assistance to the Iraqi military forces. From 2004 to 2006, NTM-I trained over 5,000 officers. From the beginning of the Mission to date, the North Atlantic Alliance has provided the Iraqi government with various military-technical means (ammunition, armoured vests, military vehicles, battle tanks and other equipment) worth a total of 110 million euros.
