I am probably being thick here but could not find in manual.
Can an open top vehicles (red armour) crew or passengers ever be hit from by small arms fire & what governs it. i.e. In adjacent hex can lob a grenade, If in higher adj hex do you have a LOS into & hence can hit with small arms, guessing no with game scale.
Also some SPG SPAA have a rear turret armour of Red 0 which I read as no armour in rear. So does fire hitting turret rear treat as a soft vehicle so a HMG has a reasonable chance of a kill?
