Well
Im not a tabnk man, or a soldier at that....And the Merkava still is secret in some ways...But here is what i know...
The Mk I and Mk II had the Older, thiner turret shape. Now, The Mk III, was a diffrent story. It had the 120mm main gun, unlike the older veraients.So the Turret had to be redesighned to some level...The earlier Mk III still had a very thin turret, but when the new generation of AT weapons(top attack), and the addition of the new fire control system, they added some armour slates and other things around and above the turret. The armour slates added around the turret vary from tank to tank according to the needs of the activety(they are modular). There are now Mk IIIs and Mk II with more extra armor. Now, the Merkava Mk IV is a whole diffrent tank. really, the body, engine electronics, turret, whole diffrent deal...
