Found an old photo and want to identify which period does it belong to and where it could have been taken or which country are these soldiers from. Found word "Brattig" on the other side, maybe someone can tell me what it means?
These are Polish Army Uniforms, starting around 1919.
Unfortunately the main wiki pages show no Uniforms of the times.
To my knowledge, these types of zig-zag collars (Polish only, but translates well to English) were in use sometime after 1918 until 1939 and are also unique to the Polish Army.
Other photo collections, without dates show the simularity of the Uniform jacket, collars and caps.
The caps called Rogatywka are also unique to the Polish Army and are still in use today.
During the Warsaw Pact days the caps and collars were used only for ceremonial occasions.
An estimated date: 1919-21, possibly during the Poland - Soviet war
