AP rounds fired by arty

[whdonnelly]

The only thing I can think of is a story an Abrams gunner told me. At long range a dark smudge on the horizon can be a tank, a truck, or a camel, so they have engaged some questionable targets more than once. Once they were engaging a target that turned out to be a land rover. After 4 hits which tore away the canvas, the windshield, and various fenders, the land rover still drove. Maybe the shock of a hit isn't absorbed by the whole vehicle, unlike an AFV. Following this reasoning, softer targets would have less critical hits than an AFV.
Would this apply to the arty rounds? Not my area of expertise, but it seems logical.
