U.S. Marines use robotic ‘mules’ in Japan assault drill

Key Points
  • U.S. Marines with the 4th Marine Regiment used Rheinmetall Mission Master Silent Partner autonomous ground vehicles during a combat readiness exercise at Camp Schwab in Okinawa, Japan.
  • The uncrewed vehicles were airlifted by CH-53E helicopters and employed in training scenarios for logistics support and casualty evacuation missions.

United States Marines with the 4th Marine Regiment, 3rd Marine Division are operating Rheinmetall Mission Master Silent Partner autonomous ground vehicles during field operations at Camp Schwab in Okinawa, Japan, as part of a combined Marine Corps Combat Readiness Evaluation.

According to a statement from the Marine Corps, the Mission Master Silent Partner vehicles were used during field operations conducted as part of the readiness evaluation at Camp Schwab. The exercise brought together Marines from the 4th Marine Regiment under the 3rd Marine Division to test operational capabilities in a realistic training environment.

During the exercise, the autonomous vehicles were transported by CH-53E Super Stallion heavy-lift helicopters. Marines airlifted the Mission Master Silent Partner systems into the training area, demonstrating the ability to rapidly deploy the uncrewed platforms alongside ground units operating in expeditionary conditions.

The vehicles were loaded with ammunition and other equipment required by Marine units conducting the field training. The systems were used to transport supplies and support Marines operating in dispersed formations during the exercise.

The Marine Corps said the uncrewed systems supplied by American Rheinmetall were integrated into training scenarios designed to support logistics operations and casualty evacuation tasks. These missions simulate situations in which autonomous systems can move equipment or evacuate wounded personnel while reducing the need for Marines to expose themselves to enemy fire.

According to the service, the systems were used in realistic operational conditions to evaluate how uncrewed platforms can assist troops in forward areas where resupply operations may face operational risks.

The Rheinmetall Mission Master platform is classified as an Autonomous Uncrewed Ground Vehicle, or A-UGV. The vehicle is designed to operate alongside ground forces and perform multiple support roles in tactical environments.

According to Rheinmetall, the Mission Master system is capable of transporting supplies, supporting last-mile resupply operations, and carrying sensors or light weapons depending on mission requirements. The vehicle can also be used for silent watch operations and other reconnaissance support tasks.

The manufacturer states that the platform is designed to operate with a high degree of autonomy, allowing it to follow troops across difficult terrain. As noted by the company, the vehicle “can follow troops as a buddy, letting soldiers get closer to the enemy without being seen or heard.”

This type of autonomous capability is intended to allow ground forces to move equipment and supplies without relying solely on manned vehicles or personnel carrying heavy loads during operations.

The Mission Master Silent Partner variant specifically focuses on logistics support roles. The system is configured to transport equipment, ammunition, and other mission supplies while moving alongside troops during maneuver operations.

In addition to supply transport, autonomous ground vehicles are increasingly being considered for casualty evacuation roles. In such missions, the vehicles can move wounded personnel away from forward positions without requiring additional Marines to remain exposed in a dangerous area.
