The British had a "HESH" Round (High-explosive squash head) in WWII.
And the winner is .... Joël.

The scab shown on the picture in the first post has been created by a 90mm H.E.S.H round (High Explosive Squash Head) fired from a distance of 1000m (3,280ft).
That was on our factory proving ground.
The round was fired by an M41 Walker Bulldog tank almost "point blank" on a steel plate target of about 4-5cm or 1,5-2 inches.
The scab thickness is about 15mm or 0.6in.
So a quarter of the steel thickness was extracted from the steel plate.
Imagine the horrible situation when it happens in the inside of a tank.
During the cold war, countermeasures were quickly found.
It consisted first in adding a layer of kevlar or other material inside the armor to avoid the scab to fly in the tank.
Later, the armor was converted into a multi layer armor to avoid the shock wave to propagate through the steel from the outside to the inside.
The H.ES.H. was almost abandoned in tank battles but is still used against buildings.
So that steel scab souvenir is almost a piece of history.
Thanks Joël !
