The Turkish Land Forces , or Turkish Army , is the main branch of the Turkish Armed Forces responsible for land-based military operations. Official claims state that the army was founded by Modu Chanyu in 209 BC, but the modern history of the army began with its formation after the collapse of the Ottoman Empire. Significant events since the foundation of the Army include combat in the Korean War and in the 1974 Turkish invasion of Cyprus, and acting as a NATO bulwark along Cold War frontiers through 1992. The army holds the preeminent place within the armed forces. It is customary for the Chief of the General Staff of the Republic of Turkey 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, which has now been regulated to an extent with the reform of the National Security Council. The current commander of the Turkish Land Forces is General Salih Zeki Çolak.
