See a lot these in some the new Military train videos. No longer just a tractor for the patriot system. Not as big. But smaller in size.
The M983A2/A4 Light Equipment Transporter (LET) tractor is mainly used to transport construction and engineer equipment. It has a 45,000 lbs. (20,430 kg) 2 speed hydraulic winch mounted behind the cab used to load the trailer. It does not have a self-recovery winch.[
