This is Revell's 1:35 Boxer, a nice, vice-free kit which is quite quick and easy to build. As with the real vehicle, the box at the back remains detachable, so I guess you have the option of swapping it for different versions if you're so inclined.
The only small quibbles I have regard the decals which didn't always adhere well, and Revell's weirdly soft plastic which, combined with some rather beefy attachment points, made some of the parts break when cut from the sprue regardless of how much care I took. Otherwise it was a very enjoyable build!
This was built almost entirely out of the box except for the optics which are made from thin strips of coloured mylar. The model was painted overall with Tamiya NATO Green from a rattle can, and the rest of the camouflage was done by airbrushing Tamiya NATO Black and NATO Brown acrylics. Weathering consisted a pin wash of dark artist oils in the recesses, and a spray of heavily-thinned sand-coloured oil paint followed by a light spattering of beige pigment and water from an old toothbrush.
All the best!
P.S. If anyone can tell me the purpose of the bright yellow and orange rectangle on the driver's hatch, I'd be much obliged. Is it a safety feature like "NO STEP" markings?
