It would only take until the 1970s and the Communist and Muslim rebellions that would force the PA into the establishment of its 2nd Infantry Division, which led to the raising of more infantry divisions all over the country, as well as the formal raising of the Army's Special Operations Command and what is now today the Armor Division. The Philippine Army was also involved in major conflicts worldwide, such as the Korean War, the Vietnam War, the War on terror, the Persian Gulf War and the Iraq War, as well as missions with the United Nations, such as the United Nations Disengagement Observer Force in Golan Heights and the United Nations Mission in East Timor. By the 2000s, the Army acquired a small aviation capability for transport purposes, with plans to include attack and transport helicopters, a rocket artillery battery unit, and a land-based missile battery system unit .
