4th Corps (Turkey)

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).

It was established in the Ankara area in 1966. 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.

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." 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.

The division's 9th Brigade was then disestablished circa 2004.
