As both Commonwealth realms, Australia and New Zealand share the customs and traditions of parades of the British Armed Forces. The friendship and cooperation of the defence services of both countries can be seen in the annual Anzac Day parades every 25 April, in memory of the namesake Australian and New Zealand Army Corps, which was heavily involved in the long Battle of Gallipoli and were the first Allied forces to land there on that day in 1915. On this day, in many major cities in these two countries, parades are held involving personnel of both the Australian Defence Force and the New Zealand Defence Force, veterans' organizations, cadet organizations, and other youth uniformed groups and personnel of the police and fire services, as well as students of schools and universities honoring many of their fallen alumni of the long campaign.
