I see the yellow sand ones as being civilian vehicles that have been pressed into service while the others are through and through civilian vehicles.
In Commercial service I wanted to keep them as bright as possible., That way they can only be so much of a distraction. I may well change the colours on the next lot to be more muted only time shall tell. For now though it is always good to have a few civilian vehicles on the board even as just acting as some form as cover for troops to hide behind.
I do have a load more vehicles to do but I feel as if I need a short break from these for a few days or a week, maybe longer we will have to wait and see.
But at least I am plugging away through the heat even if I had to do this at 5am to keep myself cool.
Quick Board update: Having laid the boards out full size they are a little small. Not giving up of course but perhaps trying to be a touch more real with the size I have. Stay tuned for the next update.
