[12] The UK Ministry of Defence announced its intention to withdraw from the Boxer programme and focus on the Future Rapid Effect System (FRES) in July 2003.

At this time the Bundeswehr also had 124 Boxer APCs, 72 ambulances and twelve driver training vehicles to upgrade to A2 status, with this work scheduled to conclude during 2024.

According to the Slovenian MoD's initial release on the subject, funding had been allocated for the procurement of 48 vehicles in 2018-2020 for the first battle group, which was expected to become operational by 2022, followed by the second in 2025.

The turretless vehicle was the first of 25 Boxers – 13 multipurpose and 12 reconnaissance variants – that were being manufactured in Germany through to 2021 to meet an early Australian capability requirement for familiarisation and training purposes.

Production of the other 186 platforms began in late 2020/early 2021 at a Military Vehicle Centre of Excellence (MILVEHCOE) constructed by Rheinmetall at Ipswich, southwest of Brisbane, that formally opened in October 2020.

The remaining drive modules being produced by WFEL will be shipped to RBSL to construct the other full vehicles in a number of variants, including the Specialist Carrier.

[48] In December 2019 Germany's BAAINBw ordered 10 Boxer in C-UAS (Counter UAS) configuration, these later designated Extended All Arms Air Defence (EAAAD).

[42][21] In June 2020 the Bundeswehr repeated an earlier statement that it would replace the Wiesel weapon carrier with a Kampfboxer mission module bringing the combination of a 30 mm cannon and Spike-LR anti-tank guided missile to the wheeled platform.

[21] In September 2021 OCCAR announced a new reconnaissance vehicle mission module for the Bundeswehr known as the Joint Fire Support Team schwer (Heavy)[49] differentiating it from the smaller Fennek scout car.

In July 2024 it was announced that Lithuania would in fact procure tracked IFVs to complement a planned new tank battalion, but some additional Boxers will still be acquired to serve as engineering vehicles, command posts, and reserve.

[51][52][42] During the Future Armoured Vehicles Survivability (FAVS) conference held in November 2023, a representative from the German Army explained that the service intended to field four medium brigades.

Serpens Deep Find radar, Mounted Close Combat Overwatch (MCCO) anti-tank vehicles, and a C-UAS capability could then follow.

On 10 April 2024 Rheinmetall Defence Australia and the Australian government signed a production agreement for 103 Schwerer Waffenträger Infanterie (sWaTrg Inf) HWC infantry vehicles.

For the sWaTrg Inf the turret will additionally be armed with the Mehrrollenfähiges leichtes Lenkflugkörper-System (Multirole-capable Light Missile System: MELLS), this the Bundeswehr's designation for the Spike LR.

The sWaTrg Inf will replace the Wiesel 1 tracked tactical direct fire-support weapon carrier in Bundeswehr service, and will equip the Army's new medium forces.

[42][21] On 24 April 2024, the UK announced its selection of the Boxer-based Remote-Controlled Howitzer 155mm (RCH 155) for the British Army's Mobile Fires Platform programme, as a successor for the AS90.

[11] The 121 Block II CRV Reconnaissance manufactured in Australia will be equipped with 2 turret-mounted Spike LR2 missiles[82] and the Iron Fist APS (Active Protection System) from Elbit.

AMAP-B modules are taken from the IBD Diesenroth (now Rheinmetall Protection Systems GmbH) AMAP modular armour package and are fitted to the vehicle with shock absorbing mountings.

The roof armour of the Boxer is designed to withstand artillery fragments and top attack weapons such as bomblets fitted with a High-Explosive Anti-Tank (HEAT) warhead.

[25] The powerpack of the Boxer consists of a MTU 8V199 TE20 water-cooled diesel engine developing (originally) 720 hp and coupled to an Allison HD4070 fully automatic transmission with seven forward and three reverse gears.

The German and Dutch Boxer ambulance variant utilise a mission module with a raised roofline providing an internal height of 1.85 m and volume of 17.5 m3.

[91] The BDR variant is able to accommodate the special equipment, tools, expendable and non-expendable supplies needed to carry out diagnoses, maintenance and minor repairs if required.

[101][102] In April 2024 the UK MoD became the second confirmed user of the type when it announced the selection of the RCH 155 for the British Army's Mobile Fires Platform programme, this a successor for the AS90.

The Bundeswehr's Joint Fire Support Team (JFST) contract was awarded in September 2021 and renderings shown by the company show Boxer (designated Joint Fire Support Team schwer (JFSTsw)) fitted with a mission module based around current in-service JFST/German Army equipment, and another fitted with equipment outlined in a JFST contract award to Thales in 2022.

The other, 121 CRV Reconnaissance are being manufactured in Australia, and will be equipped with 2 Spike LR2 missile in the redesigned turret[82] and the Iron Fist APS (Active Protection System) from Elbit.

[42][91] At Defence Vehicles Dynamics (DVD) 2024, Rheinmetall in partnership with Patria displayed as a concept demonstrator a Boxer with a NEMO 120 mm mortar turret.

Prior to delivery the Boxers were modified locally with Australian-specific communications and battlefield management systems and fitted temporarily with the Kongsberg Protector RWS that previously equipped Australian ASLAVs deployed to Iraq and Afghanistan.

Production of the remaining 186 Block II platforms was scheduled to begin in late 2022 at RDA's Military Vehicle Centre of Excellence (MILVEHCOE) at Ipswich in Queensland, Rheinmetall's biggest facility outside Germany.

[140] German Army 168 (up to) RCH 155: According to some sources selected for "ZukSysIndF program" (artillery future system, indirect fire, longer range).

[141][142] Up to 30 additional Boxer for the NNbS program (Nah- und Nächstbereichs-schutz), equipped with the Skyranger 30 turret, for command and control of SHORAD air-defence.
