The Turkish Land Forces (), or Turkish Army (Turkish: ), is the main branch of the Turkish Armed Forces responsible for land-based military operations. The army was formed on November 8, 1920, after the collapse of the Ottoman Empire. Significant campaigns since the foundation of the army include suppression of rebellions in southeastern Turkey from the 1920s to the present day, combat in the Korean War, the 1974 Turkish invasion of Cyprus and the current Turkish involvement in the Syrian Civil War, as well as its NATO alliance against the USSR during the Cold War. The army holds the preeminent place within the armed forces. It is customary for the Chief of the General Staff of the Turkish Armed Forces to have been the Commander of the Turkish Land Forces prior to his appointment as Turkey's senior ranking officer. Alongside the other two armed services, the Turkish Army has frequently intervened in Turkish politics, a custom that is now regulated to an extent by the reform of the National Security Council. The current commander of the Turkish Land Forces is General Musa Avsever. From late 2015, the Turkish Army (along with the rest of the Armed Forces) saw its personnel strengths increased to a similar level as the previous decade. Factors that contributed to this growth include the Turkish occupation of northern Syria, as well as a renewal of the Kurdish-Turkish conflict. History The Turkish Army traces its origin to the Ottoman Army. A theory accepted officially was that the Ottoman Armed Forces had been founded in 1363, when the Pençik corps (the predecessor of the Janissary corps) had been formed and, in this context, on 28 June 1963, it celebrated the 600th anniversary of its foundation. In the same year, one of the prominent Pan-Turkists, Nihal Atsız, asserted that the Turkish Army had been founded in 209 BC, when Modu Chanyu of the Xiongnu is thought to have formed an army based on the decimal system. In 1968, Yılmaz Öztuna proposed this theory to Cemal Tural, who was the Chief of the General Staff of the Republic of Turkey at the time. In 1973, when the Turkish Army celebrated the 610th anniversary of its foundation, Nihal Atsız published his claim again. After the 1980 Turkish coup d'état, the Turkish Army formally adopted the date 209 BC as its year of foundation. War of Independence The modern Turkish Army has
