The 4th Corps is a field corps of the Turkish Land Forces. Its headquarters is in Ankara, and it is directly responsible to the Commander of the Land Forces (as of 2023).[2]
It was established in the Ankara area in 1966.[1] In 1974, it appears to have been part of the Second Army. Nigel Thomas's NATO Armies 1949-87, published in 1987, attributed the 4th, 8th, and 9th Corps to the Third Army.[3]
In accordance with NATO's new strategy in the early 1990s, Turkey agreed to commit forces to NATO's ACE Rapid Reaction Corps. "Turkish Land Forces went through a very significant reorganisation program between 1991 and 1993. Within the framework of this reorganisation, most divisions were deactivated with the exception of a few. [However], the decision was made to create a new division. Thus, the old 1st Infantry Division which had been abolished many years ago was reactivated and renamed as 1 TU Mech Inf Div (1. Mekanize Piyade Tümen Komutanlığı) and attached to 4 TU Corps on 30 November 1993."[4] Major Generals tr:Oktar Ataman, promoted 1992, and tr:Orhan Yöney commanded the division. Major General tr:Ergin Sagun was also Deputy Commander of 4th Corps and Commander 1st Mechanized Infantry Division as a major-general, before he was promoted in 2001. BY 2001 the division was at Mamak in Ankara.[5]
The division's 9th Brigade was then disestablished circa 2004.
