>I don't see why people think 30 mm slugs are effective against tanks designed to resist 120 mm penetrators or shaped charges, including top armor hits.
Because tanks only have that sort of armour on their frontal aspect and turret sides, and the top armour is very thin. Even if the turret top is armoured enough it is likely the engine deck can be penetrated and produce a mobility kill.
Also, hardly anyone besides the US and extremely close allies has ultra-modern tanks like late series Abrams or the Challenger II (and I have seen no evidence that those tanks are immune to the GAU-8).
P.S. There are also cheap ways to reduce shape charge effectiveness that don't work against solid penetrators. Things like the TUSK upgrade are designed to defeat RPGs not 30mm cannon.
