I like to base my figures with the type of terrain that the Unit would have fought over.
The Kings Royal Rangers of NY and Butlers Rangers were Loyalist Regiments that fought all along the Mohawk Valley.
Their largest and bloodiest battle was at Oriskany.
The battle was an ambush that took place in the woods.
So, these figures are based as if they are in the forest of NY.
I may write a tutorial on how to do this type of base for an E Zine.
If I end up doing it, I'll post it here.
