Good to see you around Bill
According to the spec sheet, the "
Enhanced Tactical Transportability (ETT) kit allows for internal transportation in a CH-47 by reducing the standard HMMWV width by 8 inches. The kit’s new body and hood can be installed on an existing chassis, with modified components."
If you're talking about the Humvee in the last picture, it looks like a standard M1151 to me...
