 This was then compared to the actual steel thickness/angle of armor plate and also the profile/design of the various tanks.Specific weaknesses of the various tanks are also taken into account, such as the poor armor surrounding the hull machine gun on the Italian 13/40.When confronting infantry and light targets, certain weapons lack a good high-explosive shell, while others (howitzers & mortars) can wipe out infantry, but cannot confront tanks at long range.
