At this point, I gave it a first coat using VMC 897 Bronze Green. I always begin with the darkest colour I am going to use, and build my highlights from this - but this time it seemed to me that the tint was not dark enough, so I added a quick wash with GW Black Ink.
In order to achieve a weathered look on 15mm vehicles, I tend to build up the colour with multiple layers drybrushed one after the other on the shading tone - so I started with a couple of layers of VMC 888 Olive Grey, which would be the right shade for the service colour used at that time.
Then I added a little VMC 914 Green Ochre to the Olive Grey, and drybrushed it sparingly on the raised areas as a final highlight.
