"In total 25 M4 Command and Control Vehicles were built before the programme was terminated and the company agreed to store them at their York facility and try to sell them overseas with US Government approval.

Late in 2002, the US Army asked if these vehicles could be re-fielded. In the end the company and army planners mutually agreed to set aside 10 vehicles for spare parts while re-issuing the 15 remaining vehicles for possible combat service.

Beginning in October 2002, the 15 systems were fielded to US Fifth Corps (three M4s), Third Infantry Division (three M4s); First Cavalry Division (four M4s), Third Armored Cavalry Regiment (two M4s) and the First Armored Division (three M4s). Some of these units were subsequently deployed to the Middle East and took part in the invasion of Iraq.

As of late 2007 there were no plans to put the M4 Command and Control Vehicle back in production for the US Army. "
