So I am an idiot, I'm assembling my kazaks and I have col V and and a ratnik and I'm not sure who goes on which base... Help a fool out please.
You can tell by their Silhouette Attribute http://infinitythewiki.com/en/Volume_and_Silhouette_Templates Ratnik is Silhouette 5, so goes on a 40mm, Voronin is Silhouette 4, so goes on a 55mm.
