You have a couple versions there. The upper left pic is an M1120A4 LHS (Load Handling System), which can carry 10 tons of cargo on a flatrack or in a container. The other two pictures are of the M1074A1 PLS (Palletized Load System), which can carry 16.5 tons of cargo on a flatrack or in a container. They are both the latest version of HEMTT variants. Unfortunately, there are no models of these latest versions.
The closest kit to them is the Italeri M1120, which is an A2 version.
Trumpeter is also working on an M1120A2.
You can see a great build of the Italeri M1120 by Michael Koenig (165thspc here at Armorama)
here.
I also took the Italeri M1120 and combined it with the Trumpeter M983, a bunch of other parts, and some scratch-building to build an M1074. You can see it
here. I need to get back to work on it soon.
