This is one of the newer Ariadna sculpts, and what a beauty. The Spetsnaz is a new troop type for N3 (Infinity Third Edition), and their rules are as good as the model looks!
The Tactical Rocks™ were painted with a base coat of P3 Cryx Bane Highlight. Using a two-brush blending technique, I shaded them with Cryx Bane Base and then with a mixture of Umbral Umber and Black. I then touched up the base color, and added highlights by mixing some 'Jack Bone into the Cryx Highlight. Finally, to give whatever help I could for them to blend in somewhat with the base, I glazed the bottom portions of the rocks with some VMC 050 Dark Prussian Blue. Stupid Tactical Rocks™.
