K311 cargo truck
1 1/4–ton cargo truck
From Wikipedia, the free encyclopedia
The K311 is a 4x4 multipurpose 1 1/4–ton class cargo truck developed for the Republic of Korea Armed Forces, and was introduced in 1980. It is commonly known as 4-5 (5/4) ton (4-5 톤) or military Dodge (군용 닷지), because it replaced and had similar appearance with Dodge M37. It is a modernized version of the American Kaiser Jeep M715 truck, which was also designed with an intention to replace the M37 truck.[note 1]

General Characteristics
K311A1
In June 2000, Kia Motors signed a deal with Turkish company, and began product improvement program (PIP) on K131, K311, and K511 series. The export plan was cancelled due to 2001 Turkish economic crisis; nonetheless, Kia Motors, which has already spent a lot of money, decided that it could not stop the project, and invested a total of 10.43 billion KRW to finish the program by April 2003.[7]
To distinguish K311 and K311A1, check the number of front windshields (two: K311 or one: A1), the number of wipers (two: K311 or three: A1), tire thickness (wider: A1), engine (V6: K311 or V4: A1), and bullbar design.
K311A2
The K311A2 is a second upgrade variant of the K311 first revealed at DX Korea 2018. It has a hardtop roof on driving section, air conditioner, and navigation system as a default.[8] The vehicle is unlikely to be adopted by South Korea as K311s are being replaced with K151 series.

Notes
- It is unclear what kind of contracts were made due to lack of sources. There is a possibility that the U.S. government provided the blueprint for free to South Korea to keep the supplies manufactured, similar way the U.S. did to other military gears that are no longer produced in the U.S. but used by South Korea.
- Kia Group acquired Asia Motors in 1976. Later, both Asia Motors and Kia Motors were owned by Hyundai in 1998.
