Rare F-4E photo of 36th TFS still wearing the UK tailcode. In 1974, the 36th TFS had just transitioned from the F-4D to the F-4E, while with 3rd TFW at Kunsan, RoK. In that same year, the unit was transferred to the 51st Composite Wing at Osan, RoK, where the OS tailcode was applied. Location where this picture was taken needs confirmation.

The UK tailcode transferred from 356th TFS at Misawa (green fin color) to 36th TFS at Kunsan (red fin color) in March 1971. This is a F-4D from the latter unit. It was later delivered to the South Korean air force.
