The implementation of the Machine Care Plus® service in support of transmission units fitted to British Army Challenger 2 main battle tanks and Challenger Armoured Repair and Recovery Vehicles (CRARRV), which commenced in February 1999, is now complete. It includes a secure communications network linking Challenger 2 tank regiments and relevant support and training organisations in the UK, Germany and Canada. Over 500 assemblies are currently supported by AES’s condition based asset management service.
