The last Boy Scout National Jamboree was at Fort AP Hill in 2010. I remember the base commander and his top brass with some vips arriving at a function that I was at in Suburbans that appeared to be civilian except for the huge white domes sticking out of the roofs and extra antennas all aimed at Area 51.
Saw them several times through the 2 weeks as those satellite antennas made them hard to blend in. The base commander made daily visits of the entire jamboree site. These were definitely army vehicles belonging to the base top echelon.
I do not remember them being painted camo or green but maybe blue and black?
I suspect the military does buy civilian models off the shelf and adapts them for VIP, special purpose etc in low numbers as need.
Yours is still a cool rig and I know many of us wish we had the $ at the time it came for sale.
