Hello all,

This is a medal I bought but with another ribbon, not white but red/white (vertical).
Krzyż Związku B. Wojskowych i Rez.R.P. w Belgii

I'm not sure what it is.

Official/unoffical medal?
Polish troop in Belgium? Why awarded?
When awarded?
Ribbon is supposed to be white or red/white?

Any information on this medal would be appreciated. Thanks!
