The Boxer RCH 155 variant, designed to support mobile artillery fire, is expected to be included in the British Army’s mobile fire platform program, with 96 units planned. This variety of configurations underscores the Boxer’s adaptability, ensuring it meets the unique demands of modern warfare.

The Boxer 8×8 armored vehicle has been undergoing extensive testing since 2023, with trials designed to ensure its readiness for deployment within the Armoured Brigade Combat Teams. These trials, led by Defence Equipment and Support (DE&S), began with industry testing in the summer of 2023 and transitioned to formal customer trials in the fall. Each phase has rigorously assessed the vehicle’s adaptability, reliability, and compatibility with British Army requirements.

The key tests for the Boxer included mobility trials across a variety of terrain types, designed to gauge its agility, stability, and speed across rough, uneven surfaces. Tests have confirmed the vehicle’s ability to cover long distances quickly, essential for a vehicle that must keep pace with the Army’s Strike Brigades during rapid deployment scenarios. Role-specific tests were conducted for each variant of the Boxer, ensuring that each configuration can meet the demands of its intended function. For instance, the infantry carrier variant underwent tests to confirm its efficiency in transporting soldiers safely, while the command-and-control variant was evaluated for its ability to maintain seamless communication under combat conditions.

A live-fire trial tested the Boxer’s capacity to integrate weapon systems, such as heavy machine guns and anti-tank missiles. These weapon systems, essential to the Boxer’s combat capabilities, demonstrated reliable functionality under simulated combat conditions, confirming the vehicle’s readiness for active deployment.

Seawater Fording Trial: Proving the Boxer’s Aquatic Prowess

The recent fording trial at Instow Beach provided a crucial test for the Boxer’s amphibious capabilities. Successful water fording, defined as the ability of a vehicle to traverse through water obstacles without extensive preparation, is essential for mechanized infantry vehicles expected to operate in varied environments. Fording ability is particularly important in scenarios where the vehicle might encounter rivers, marshes, or flooded terrains during deployment.

The Boxer was put through a seawater fording trial that evaluated its stability, traction, and water resistance. The trial’s success demonstrated the vehicle’s resilience to water ingress, as well as the reliability of its onboard systems, including the engine, electrical components, and weapon systems, which remained unaffected by exposure to seawater. Such resistance to water penetration is essential in ensuring that the Boxer maintains its combat readiness, even in environments where traditional wheeled vehicles would struggle.

Fording capabilities significantly enhance the operational reach and flexibility of the Boxer vehicle. By being able to cross water obstacles without external support, the vehicle eliminates the need for bridge-building equipment, reduces logistical dependencies, and ensures rapid mobility in environments where a slow crossing could compromise mission success. This capability also enables the Boxer to maintain formation with other elements of the Brigade Combat Teams, including the Ajax infantry fighting vehicle (IFV) and Challenger 3 main battle tank (MBT), which are similarly designed for high mobility across diverse terrains.

Mechanized Infantry Vehicle (MIV) Role and Brigade Combat Team Integration

The Boxer is expected to operate within the British Army’s Brigade Combat Teams, where it will support infantry, engineering, reconnaissance, and command roles. The vehicle’s integration into these teams reflects the Army’s focus on enhanced combat flexibility, rapid deployment, and multi-domain operational effectiveness. The British Army has specifically stated that while the Boxer will take on some roles previously served by the Warrior infantry fighting vehicle, it is not a direct replacement. Instead, the Boxer is intended to fulfill a unique set of capabilities in line with modern mechanized infantry needs.

Minister for the Armed Forces Luke Pollard has confirmed that the Warrior will remain in service until additional systems and capabilities are introduced over the decade. This continuity reflects the British Army’s phased approach to modernization, wherein the Boxer serves to supplement rather than replace existing systems. The phased integration of the Boxer into Brigade Combat Teams will allow the British Army to retain an effective fighting force during the transition while gradually adopting the advanced capabilities of the new fleet.

Enhancing Strike Brigades with Modular Adaptability

The modular adaptability of the Boxer provides the Strike Brigades with a versatile and highly customizable vehicle platform that can be reconfigured as mission demands change.
