New Zealand soldiers served with distinction in the major conflicts in the 20th century, including the Second Boer War, World War I, World War II, the Korean War, the Malayan Emergency, Borneo Confrontation and the Vietnam War. Since the 1970s, deployments have tended to be assistance to multilateral peacekeeping efforts. Considering the small size of the force, operational commitments have remained high since the start of the East Timor deployment in 1999. New Zealand personnel also served in the First Gulf War, Iraq and Afghanistan, as well as several UN and other peacekeeping missions including the Regional Assistance Mission to Solomon Islands, the Sinai, South Sudan and Sudan.
