Military parades The Republic of China held their first military parade on 10 October 2007 for National Day celebrations since 1991. Previous parades were halted in an effort to ease the tension with the PRC. The parade was aimed at easing worries that the armed forces might be unprepared for a conflict with the PRC. The parade consisted of indigenous missiles, U.S. Patriot II and Avenger anti-missiles systems, U.S.-made F-16s, French-made Mirages and Taiwan-made IDF fighters.
