On 4. November 2019, the OCCAR-EA Director and the ARTEC Chief Executive Officers signed a contract for the procurement of more than 500 BOXER vehicles on behalf of the United Kingdom of Great Britain and Northern Ireland (UK).

The delivery of the first two Lithuanian VILKAS Infantry Fighting Vehicles took place on 9 July in Vilnius, Lithuania. This is an historical milestone for the Lithuanian Armed Forces but also for OCCAR, as it demonstrates the level of support provided by the organisation to its customers be it OCCAR Member States or OCCAR Programme Participating States.

On 7th February 2019 another major milestone in the BOXER Programme took place: the delivery of the 500th BOXER vehicle.
The vehicle was handed over by the manufacturer KMW at its facilities in Munich and it is a GTFzA2 variant (Gruppentransportfahrzeug).

The UK will re-join the BOXER Programme with the intention  to equip the Army with the 8x8 BOXER vehicles to modernise its vehicle's fleet and to fulfil the requirements of the Mechanised Infantry Vehicle (MIV) Programme.
