Weight rating for Military trailers is normally the approved weight off highway.
My M101 (3/4 ton) has 2 ratings on the info tag. 1500lbs off road, 2200 HWY. And I have greatly exceeded that many times. Probably 3000+ off road once
Maybe there is even more beyond what the trailer can hold for the military but a certain level it will still preform at. Goes back to what the Jeep can pull again
Just thinking out loud....
