Been having a 2 week break to do some DIY, so just got back to this project.
I airbrushed the HEMTT orange, a bit wild I know, but rather than an ex military truck I thought that one might be in use as a haulage or logging lorry, hence the orange livery!
I also added a bit more detail to the top structure, with some benchs, gun mounts and some mesh and slat protection. Once this was done I sprayed it with various rust colours, I'll add some more detail by hand.
