K-3

The Daewoo Precision Industries K3 was developed in South Korea as a squad automatic weapon and light machine gun chambered for 5.56 x 45 mm NATO ammunition. It entered service as South Korea sought to reduce dependence on foreign machine guns and standardize infantry firepower around domestic small-arms production. The weapon became associated with Republic of Korea Army squad support and was later exported to several users.

Technically, the K3 is a conventional 5.56 mm light machine gun intended to provide sustained suppressive fire at squad level. It uses a lightweight support-weapon layout with bipod use, infantry portability, and compatibility with NATO ammunition logistics. Its design priority is not heavy tripod fire but giving a squad more automatic fire than riflemen can provide, while remaining lighter and easier to move than a general-purpose machine gun.

Operationally, the K3 filled the automatic-rifle and light-machine-gun role in South Korean infantry units. It offered domestic support-weapon production and common ammunition with rifles such as the K2. Over time, user feedback and modernization needs led to replacement planning and the introduction of newer K15 systems. The K3 remains significant because it marks South Korea's move from imported support weapons toward a local infantry small-arms ecosystem.
