Which country(ies) in particular are you referring to?
Romania, Bulgaria, Moldova, Georgia, Ukraine.
They weren't necessarily fatasses but they were all just a little pudgy and slow. Their rank structure is fricked. Very little NCO leadership. However they are working on that.
Macedonia and Albania.
These guys for whatever reason were all in fairly good shape and well disciplined. Perhaps I just worked with better units from those countries. However the Albanians all had 1 female in each rifle platoon. If you looked at their Table of Organization she was listed as "female personnel."
That's no lie. I'm not sure exactly what her job was but I have my suspicions.
