Hello, I don´t understand how it works the reserve roll for "Infantry unit equipped with a Machine Gun (SWAs 7 - Machine Gun)", do you need two stars to use it or only one infantry die without star?
I think it's pretty clear from the description that the German player can use a flag + star result let's you put a machine gun, mortar or anti-tank gun on one of your infantry units already on the board.
It´s the same in the poland campaign with the tanks and grenades dice
In the 'Fall of Poland' Campaign, when the Allied (Polish) player rolls a grenade, he can use it to get either an infantry or an armor unit as reserves. When he rolls it in combination with a star, the unit (infantry or armor) he chooses will be 'elite' (Troops 2 - Specialized Units).
When het throws an armor result, the unit can contain maximum 2 figures, even if he threw an armor and a star result, which would normally grant him an elite armor unit containing 4 figures.
I'm not really sure if using a grenade result as an armor result also gives an armor unit with only 2 figures...
