In the example on 8.2: Small Arms vs Gun. it says "The Rifle Squad cannot affect the AT Gun itself".
...
I think most of the time, firing infantry against armored targets is just slowing down the game.
Now wait just a cotton pickin' minute, there.
Suggesting that infantry don't attack guns is not right.
No, no, no. The AT gun's second biggest nemesis, right after artillery, was enemy infantry.
But not because they broke the guns. The hard shiny bits were not particularly vulnerable to rifle fire. But the soft squishy bits very much were.
From Chapter 8, page 8.2:
Small Arms vs. Guns
Small Arms fire will have no effect
upon the gun itself but the attack will certainly
annoy the crew. Work out the results
as an attack vs infantry as outlined above.
NOTE: Depending on the direction of fire
and the particular gun being crewed, there
may be a gun shield that may provide cover.
So yes, a squad of guys with M1 Garands, a BAR and some hand grenades are not going to break a Pak40. But they can certainly "annoy" the crewmen around that Pak40. As in "annoy" them to death, even.
