One more confirmation of Rosomak squad - a picture that was posted recently on one fb group about Polish military. There was also posted an information, that squads really have 5 men, with an option for 6th man from reserve forces...
Of course, we should stick with a bigger number.
(Just to explain, the first vehicle has 7 men, with platoon commander and radio operator. "Załoga" is a crew.)
There are no snipers in a platoon indeed, they can be assigned from company level.
