Apart from the pointy hats, what determines them as Red infantry? Could they be used for WW1?
Unfortunately, these figures are not suitable for the period of the First World War. At least - without significant refinement of some of them. The officers are dressed in leather jackets, which is typical of the Bolsheviks, but not for the officers of the Imperial Army. In addition, they have a "red commander's sign" on their chests. Most of the caps in the set have a picture of a cockade-star, and a fur hat-ribbon (should be red), which determines their belonging to the Bolsheviks. Figures have insufficient equipment for the war, which is characteristic of the civil war in which all sides lacked weapons and equipment.. Figures do not have sapper shovels, flasks, bowlers, two figures are dressed in shoes made from wooden strips - bast shoes.
