I haven't come across any [reasonable] models of current/recent use military vehicles.
I refer particularly to logistics vehicles, rather than armour.
For the past 15/20 years the military have utilised DROPS systems...ie demountable rack off-loading and Pickup systems.
The DROPS MMLC [15 tonne} 8 wheelers (LeyDAF) or even the Foden IMMLC is nowadays a vital logistics military vehicle...more so than any other.
Just take a look at any newsreel footage of military establishments in Iraq, and DROPS is all over the place.
One of the aspects of DROPS is the Simple Rail Transfer Equipment...or SRTE.
Over the years, this has taken the form of either an artic-mounted unit, or a unit built to be mounted on the back of a DROPS MMLC.
The kit is designed to lift loaded flatracks (the demountable loadbeds) off flatcars, and transfer them to the ground, for a DROPS vehicle to back onto and pickup.
They 'look' a bit like huge ship's lifeboat davits.
Container-handling plant is also used..right up to huge 80 tonne Kalmars....paint them green, and have several in bits, broken down!
So military rail loads could be flatracks...[with vehicles secured on them?] or containers?
we have containers readily available......but what of the racks?
