His Majesty's Armed Forces (HMAF) is the military of Tonga. It is composed of three operational components and two support elements (logistics and training groups). The mission of HMAF is to: "Defend the sovereignty of the Kingdom of Tonga". The HMAF is partially supported by defence co-operation agreements with Australia, the United States, China, India and New Zealand. The co-operation aims at capacity development through training of HMAF personnel in leadership, academic and trades while support for infrastructure development is another part of the security co-operation. In recent years, members of HMAF have supported Coalition of the Willing in Operation Iraqi Freedom, the International Security Assistance Force in Afghanistan, and the Regional Assistance Mission to the Solomon Islands. History Tonga participated in World War I, as part of the New Zealand Expeditionary Force. The Tonga Defence Service (TDS) came into existence at the beginning of World War II in 1939. In 1943, New Zealand helped train two Tongan contingents of two thousand personnel who fought in the Solomon Islands Campaign. In addition, New Zealand and US troops were stationed on Tongatapu, which became a staging point for shipping. At the end of World War II, the TDS was disbanded, but was re-formed in 1946. Former Prime Minister Prince Lavaka Ata 'Ulukalala (now King Tupou VI) joined the naval arm of the Tonga Defence Service in 1982 and became Lieutenant-Commander of the defence force in 1987. From 1990 to 1995 he commanded the PPB VOEA Pangai and his time in charge included peacekeeping operations in Bougainville. In 2002, TDS soldiers were deployed as part of a multi-national regional peacekeeping force in the Solomon Islands. In July 2004, a forty-five personnel contingent of the TDS served in the Solomon Islands. A third contingent was sent in July 2005. This contingent consisted of thirty-three TDS troops, and was expected to remain four months. In March 2003, military-to-military talks began between Tonga and the United States about Tonga providing personnel for the Multinational force in Iraq. Support arrangements were finalised in May 2004. Forty-five Royal Tongan Marines, led by the Chief of Defence of the Tonga Defence Services, Colonel Tau'aika 'Uta'atu, departed Tonga on 13 June 2004. From July 2004, the Royal Tonga Marines were augmenting the 1st Marine Expeditionary Forces (MEF) in the Al Anbar Province of Iraq. The Royal Marines supported the 1st Marine Division's security and stabilisation mission at Camp Blue
