I have a question regarding the GUARD THE CONVOY special ability. I have put a Matsu Destroyer with this SA together with a Chitose auxiliary. During the game there was a situation, that an allied cruiser wanted to shoot with ER4 at that auxiliary. Problem was, that the Auxiliary can‘t be attacked because the Matsu must be attacked first due to GUARD THE CONVOY. The Matsu can‘t be attacked with ER4 because it is a destroyer. So is it really understood correctly that if I put the Matsu with any friendly auxiliary unit in the same sector, that the auxiliary is immune then to ER4 attacks because the destroyer prevents it with the GUARD THE CONVOY ability (No ER shots allowed against destroyer)?
The logic is that it has to shoot the DD first, and the immunity to ER is essentially just an automatic miss. Think of it that the enemy fired at Matsu and missed.
