 In addition, the Semovente da 90/53 had little or no armour in most areas.Because these vehicles were designed to operate far enough away from enemy vehicles to not be subject to incoming fire, this was initially not considered a problem.The small ammunition capacity of the vehicle—six rounds—was also a problem, necessitating the creation of special ammunition carriers out of Fiat L6/40 tanks, one accompanying each Semovente da 90/53 in the field.
