This is a Tatra PR3333 6×6 truck, outfitted with a hook-lift system and depicted in Dutch Army specification by Flickr’s Arian Janssens.
We’re not sure what’s in the big green box it’s carrying, nor the second one towed behind via the neat drawbar trailer, but as we assume it’s army stuff we probably wouldn’t understand anyway.
The truck, trailer, and boxes are all superbly built, and there’s more to see of all components at Arian’s photostream. Click the link to take a look.
*Points for us for not going down the ‘Dutch Hooker’ route with this post! Until now. Damn.
