The new 1/72nd scale Imex Americans from the Mexican American War are a good set. I have so far purchased two sets of them and elements of two photos are shown here. I am very happy with the set, they troops are flash free, well animated, good size and good poses. Here you can see a few of them advancing along a fortress wall, and down along the moat.
This officer is firing his pistol and waving his sword, a great action figure. There are two flag guys in the set, one standing being wounded and one kneeling shooting a pistol. The pistol guy has his flag arm as a separate piece.
