Had not seen that version - but you seem to be correct - however the DOD commnet stands: not active US mil unit nor vehicles.
From the posted article:
Reached by email, Lt. Jacqui Maxwell, a spokeswoman for Naval Special Warfare Group Two, released a statement confirming that the vehicles captured on video and cameras were based in Fort Knox, Ky., and were driven by members of an East Coast Naval Special Warfare unit. At the time, she noted, the convoy was traveling between two military training areas.
