"The Midnight Gang's assembled ...." (Bruce Springsteen)
Can only agree with Alex! I had trouble seeing the use of these figures, but you have showed me some uses!
They put me in mind of WW! trench raiders - perhaps it's the assortment of weaponry? Was wondering about a low relief diorama: cutaway of a mine or counter-mine?
Well in my mind these figures could be making an ambush like this very nice diorama up with one or two figures placed on high ground.
