Can friendly units block Anti-Tank fire? My first reaction is no, since Blocked Fire is covered under Rule
10.0: Direct Fire. Anti-Tank Fire is under Rule
11.0: Anti-Tank Fire, and blocked fire is not mentioned anywhere in Rule 11.
Rule
7.24: Blocked Fire would also seem to apply, but it mentions only Direct Fire being blocked.
As an example, in the diagram under Rule
11.12: Crossfire, would a Soviet infantry unit in hex 0612 or 0611 block the KV-1 from firing? What about a Soviet AFV in either hex?
