1903, established the operation and command structure of the Australian Army. In 1911, the Universal Service Scheme was implemented, introducing conscription for the first time in Australia, with males aged 14–26 assigned into cadet and CMF units; though the scheme did not prescribe or allow overseas service outside the states and territories of Australia. This restriction would be primarily, and continually, bypassed through the process of raising separate volunteer forces until the mid-20th century; this solution was not without its drawbacks, as it caused logistical dilemmas. World War I After the declaration of war on the Central Powers, the Australian Army raised the all volunteer First Australian Imperial Force (AIF) which had an initial recruitment of 52,561 out of a promised 20,000 men. A smaller expeditionary force, the Australian Naval and Military Expeditionary Force (ANMEF), dealt with the issue of the German Pacific holdings. ANMEF recruitment began on 10 August 1914, and operations started 10 days later. On 11 September, the ANMEF landed at Rabaul to secure German New Guinea, with no German outposts in the Pacific left by November 1914. During the AIF's preparations to depart Australia, the Ottoman Empire joined the Central Powers; thereby receiving declarations of war from the Allies of World War I in early November 1914. After initial recruitment and training, the AIF departed for Egypt where they underwent further preparations, and where the Australian and New Zealand Army Corps (ANZAC) was formed. Their presence in Egypt was due to the planned Gallipoli campaign, an invasion of the Ottoman Empire via Gallipoli. On 25 April, the AIF landed at ANZAC Cove, which signaled the start of Australia's contribution to the campaign. Following little initial success, fighting quickly devolved into trench warfare, which precipitated a stalemate. On 15 December 1915, after eight months of fighting, the evacuation of Gallipoli commenced; it was completed 5 days later with no casualties recorded. After regrouping in Egypt, the AIF was split into two groups and further expanded with reinforcements. This division would see a majority of the Australian Light Horse fight the Ottomans in Arabia and the Levant, whereas the rest of the AIF would go to the Western Front. Western Front The AIF arrived in France with the 1st, 2nd, 4th and 5th Divisions; which comprised, in part, I ANZAC Corps and, in full, II ANZAC Corps. The 3rd Division would not arrive until November 1916, as it
