The Turkish Armed Forces withdraw from northern Iraq after assisting the Kurdistan Democratic Party in the Iraqi Kurdish Civil War.

Operation Hammer (Turkish: eki Harekt) was a cross-border operation by the Turkish Armed Forces into northern Iraq between 12 May and 7 July 1997 against the Kurdistan Workers' Party (PKK).

The operation's objectives were to destroy PKK units in northern Iraq, to strengthen Massoud Barzani's Kurdistan Democratic Party in its ongoing Civil War with Jalal Talabani's Patriotic Union of Kurdistan in the hope that the KDP would prevent further PKK raids into Turkey, and to counter Iranian influence in the region as Turkey accused Iran of supporting the PKK, and over 2,000 Iranian forces had entered Iraqi Kurdistan that year to aid the PUK.The operation ended unsuccessfully and it led to another operation, Operation Dawn (1997).

The Turkish Armed Forces (TAF; Turkish: Türk Silahlı Kuvvetleri, TSK) are the military forces of the Republic of Turkey. Turkish Armed Forces consist of the General Staff, the Land Forces, the Naval Forces and the Air Forces. The current Chief of the General staff is General Yaşar Güler. The Chief of the General Staff is the Commander of the Armed Forces. In wartime, the Chief of the General Staff acts as the Commander-in-Chief on behalf of the President, who represents the Supreme Military Command of the TAF on behalf of the Grand National Assembly of Turkey. Coordinating the military relations of the TAF with other NATO member states and friendly states is the responsibility of the General Staff.

The history of the Turkish Armed Forces began with its formation after the collapse of the Ottoman Empire. The Turkish military perceived itself as the guardian of Kemalism, the official state ideology, especially of its emphasis on secularism. After becoming a member of NATO in 1952, Turkey initiated a comprehensive modernization program for its armed forces. The Turkish Army sent 14,936 troops to fight in the Korean War alongside South Korea and NATO. Towards the end of the 1980s, a second restructuring process was initiated. The Turkish Armed Forces participate in an EU Battlegroup under the control of the European Council, the Italian-Romanian-Turkish Battlegroup. The TAF also contributes operational staff to the Eurocorps multinational army corps initiative of the EU and NATO.
