THE ACHILLES' HEEL OF TANK

The new protection devices are applied in the first instance to the front and sides of the tank. The roof, on the other hand, is far more difficult to protect.

And because the armour on the roof is only a fraction of the thickness of that on the sides and front, there is every justification for asserting that the roof is the Achilles’ heel of the tank.

But conventional anti-tank missiles simply cannot strike the roof. To do this, the missile must have a warhead which, upon detonation, directs its shaped-charge warhead jet downwards onto the target. Just like BILL.
