Note that this is a reaaaally easy and discrete "mud" (more like dirt) done for the Kursk summer battle (and now looking at it I would do a lot of things differently in this model), depending of what part of the year/theater you wanted to do I would go heavier. In the background you can see the mud product and a wet splashes that would give a darker and shinier finish than the loose ground if you want to keep it "thin"
