Anti-Tank guns OPP fire....One shot?

[saracv3]

And now for an additional thought or two: Turrets w/ their ability to swivel quickly might justify two shots, but AFVs include Assault Guns and Tank Destroyers. These have no turrets, but also get that 2 shot advantage, correct?

And what of Opportunity Fire and AT? One gets two shots per turn w/ that right? Even the supposedly cumbersome 88mm is pretty fast in the reload.

Now I have very little wisdom, and am no wise guy. Just asking questions here.
