A single IFV will be used for maintenance training. The first two vehicles (driver training configuration) were delivered to Lithuania in December 2017. The first two Boxer in IFV configuration were delivered on 25 June 2019 and at this time the Lithuanian MoD stated that 15 vehicles would be delivered to Lithuania in 2019, and that all 89 IFV variants would be delivered by the end of 2021. In June 2017 it was announced that the Bundeswehr's Boxer A1 fleet would be upgraded to A2 standard. Of the original German Army order most were delivered in A1 configuration, however 40 APC and 16 command post had been delivered in A0 configuration. These were subsequently upgraded to A1 configuration. The first A2 configured Boxer was delivered in June 2015. According to ARTEC, the differences between A1 and A2 configuration are relatively minor electrical and mechanical engineering changes.The A2 standard resulted from operations in Afghanistan and incorporates changes in the drive and in the mission module that include preparation for the integration of a driver vision system, changes to the stowage concept in both modules, changes to the gearbox, integration of a fire suppression system, modification of the RCWS, interface for an IED jammer, satellite communication system and other minor modifications." The latest variant is the A3, the British the first customer for A3 in its entirety. On 4 July 2017 ARTEC awarded the then Rheinmetall MAN Military Vehicles (RMMV) a contract to upgrade 38 Bundeswehr Boxer command vehicles to A2 configuration. The value of the contract was stated to be €21 million. Work is scheduled for completion in mid 2020. At this time the Bundeswehr also had 124 Boxer APCs, 72 ambulances and twelve driver training vehicles to upgrade to A2 status. In February 2018 it was announced that Slovenia had selected the Boxer as the basis for two new mechanised infantry battle groups. Confirmation of a final proposal schedule for the procurement, which will be via OCCAR, was originally scheduled for September 2018. In November it was revealed that pricing issues had impacted the Slovenian timeline and that a new proposal from industry was pending. According to the Slovenian MoD's initial release on the subject, funding had been allocated for the procurement of 48 vehicles in 2018-20 for the first battle group, which was expected to become operational by 2022, followed by the second in 2025. The desired total is reported to be 112 Boxer (96 IFV, 16 mortar) plus a small number of driver training vehicles.
