From: "Tim Jeffreys", [EMAIL PROTECTED] The effective protection of sloping armour is considerably more than just the effective geometric thickness, due to the effect of cavitation. As a shot strikes a sloping plate, the nose is given a "nudge" in the direction of the slope, such that the shot begins to bias along the slope, increasing the amount of armour that the shot has to travel through on a curved path. Sufficiently sloping plates that are not penetrated may actually show "divots" of armour missing. This is all well and good until some unsporting so-and-so comes along and bangs a hollow charge (or HESH come to that) warhead into your beautifully sculpted sloping plates, whereupon all that slope becomes about as useful as a pitcher of warm spit (though I guess you could try to put the fire out with the latter). Then it's back to the drawing board for the dangly skirts, Chobham honeycomb and the active disruptive plates....
