K311 cargo truck

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. The truck was produced by Asia Motors until Hyundai merged the company with Kia Motors in 1999. The KM450 is an export name designated by Kia Motors, and the name is used widely outside of South Korea for both old and new variants.
