The Infantry Combat Rifle (ICR) (Zhenian: 보병전투소총), formerly known as the Next-Generation Infantry Weapon (Zhenian: 차세대보병화기) during its development phase, is a line of short-stroke piston-operated, selective-fire assault rifles with a rotating bolt from Zhenia. Constructed to be a modular rifle, it features high modularity in barrel and caliber changes, as well as its adaptability to various circumstances all while using the same platform. Like its predecessor, the Z620 series, its initial baseline variant, the ICR-L, was developed with the Munmu 6.8 mm rounds in mind, although other variants using different calibers exist. Introduced in 2004, it has been designated as the primary service rifle of the Greater Eastern Union Defense Forces since then, while it has also seen service in other governmental branches and armed forces around the world.
Development
Although having received significant updates in its capabilities over the years, the Ministry of Defense was discussing potential replacements to the Munmu Z620 series.

Variants
- ICR-L: Standard assault rifle variant, chambered with the 6.8 mm Munmu rounds, used by the Greater Eastern Union Army.
- ICR-LS: Carbine version derived from the ICR-L, optionally using .300 blackout rounds instead of the usual 6.8 mm Munmu rounds.
- ICR-H: Battle rifle variant chambered with 7.62 x 51 mm NATO rounds. It is capable of automatic fire, although semi-automatic fire is used more commonly for its mission profile.
- ICR-M: Squad automatic weapon variant of the ICR, derived from the ICR-L and thereby chambered with 6.8 mm Munmu rounds.
- ICR-S: Designated Marksman Rifle variant dubbed 'ICR-Sharpshooter', capable of semi-automatic fire, with a adjustable fixed stock and pistol grip. Primarily based on the ICR-H, some units have been observed with built-in suppressors.
