I make my generics distinct with bases. In this case, a trench gunner and an Endor-y forest scout. I gave the barbed wire just a touch of Blood for the Blood God from the scout setting it up in a rush. My Endor guy has Army Painter Summer Undergrowth and various nicks from wildlife. I stuck a tiny stick on the power box like an Ewok hit it with an arrow, but that fell off. Remembering "Time and Punishment," I stuck some Nurgle's Rot on his elbow and underside of boot from an imagined encounter with a very large mosquito. I have some camouflage netting that I might throw over the cannon.
