- The U.S. Army deployed M1304 Stryker armored vehicles equipped with 30mm cannons to Busan, South Korea as part of a rotational deployment.
- The vehicles are intended to help incoming U.S. units rapidly establish combat capability and integrate with Republic of Korea forces during joint operations.
The United States Army has deployed M1304 ICVVA1 Stryker infantry carrier vehicles to South Korea, with the armored vehicles arriving at the port of Busan as part of a rotational deployment, according to a service statement.
The deployment introduces a heavier-armed Stryker variant equipped with a 30mm cannon designed to increase combat capability for U.S. units operating on the Korean Peninsula.
The arrival of the M1304 ICVVA1 Stryker vehicles supports the rapid integration of incoming U.S. forces with South Korean allies during routine rotational deployments. Delivering armored vehicles directly through Korean ports allows deployed units to establish operational readiness soon after arrival.
“Delivering combat vehicles through Korean ports ensures incoming units quickly establish combat capability and integrate with Republic of Korea allies during rotational deployments,” the statement said.
The M1304 ICVVA1 is a variant of the Stryker infantry carrier vehicle equipped with the Medium Caliber Weapon System, a turret-mounted 30mm cannon that provides greater firepower compared with earlier Stryker models. The weapon system allows the vehicle to engage armored targets, fortified positions, and enemy infantry at longer ranges.
The Oshkosh Defense’s Medium Caliber Weapon System (MCWS) mounted on the vehicle is based on Rafael Advanced Defense Systems’ SAMSON family of remotely operated turrets. The turret integrates a stabilized 30mm automatic cannon that can be controlled from inside the vehicle, allowing the crew to operate the weapon without exposing themselves to enemy fire.
Stryker vehicles are a key component of U.S. Army Stryker Brigade Combat Teams, which are designed to provide mobile, medium-weight ground forces capable of rapid deployment. The eight-wheeled armored vehicles offer a balance between mobility and protection while transporting infantry units and supporting equipment.
The M1304 variant was developed to increase the lethality of Stryker formations after operational experience highlighted the need for heavier onboard firepower. Earlier Stryker infantry carrier vehicles were equipped primarily with machine guns or grenade launchers, which limited their ability to engage certain armored threats.
By integrating the 30mm cannon, the ICVVA1 provides units with a weapon capable of engaging light armored vehicles and fortified positions while supporting infantry operations. The system also improves the vehicle’s ability to conduct reconnaissance and provide direct fire support during ground operations.
Stryker vehicles are frequently used in rotational deployments because their wheeled design allows them to move quickly over road networks while requiring less logistical support than heavier tracked armored vehicles. This mobility allows units equipped with Strykers to reposition rapidly during training or operational missions.
The M1304 Stryker variant, with its 30mm cannon, represents a modernization step for Stryker-equipped formations. The upgraded weapon system provides greater engagement capability while maintaining the mobility and transport capacity associated with the Stryker platform.

Korea, Feb 4. For some reason, public affairs staff keeps labeling MCWS as the M1296 Stryker Dragoon, the two are completely different.”
