Last year I modeled a soldado using ZBrush. The model used too many polygons to be practical in my Alamo model and I never went through the process of changing the topology and rigging it for animation.
The new model is based on the MakeHuman tool. The clothes were modeled in Blender and textured using Substance Painter. The level of detail is suitable for a display in which the character is less than about 500 pixels. The character (with gun) uses about 8K vertices but I could probably reduce it to about 6K without losing much detail. It is completely rigged and can be posed and animated.
Here is the model in SketchFab: Soldado in 3D
