So, I had a situation come up yesterday.
There was a Z-95 in range 1 of the following:
- Valen Rudor ("While an enemy squadron is engaged with another squadron, it cannot attack you.")
- A TIE Bomber (Heavy)
- An Interdictor.
The Z-95 was engaged by enemy squadrons. ("While a squadron is at distance 1 of one or more enemy squadrons, it is engaged with all of those enemy squadrons - pg. 6 RRG)
Since it was engaged with a non-heavy squadron (Valen), it could not shoot at the ship. ("When a squadron attacks, it must attack an engaged
squadron if possible rather than an enemy ship.")
However, it could not attack Valen Rudor.
The TIE Bomber was Heavy ("You do not prevent engaged squadrons from attacking ships or moving." - pg. 12 RRG). Therefore, the TIE Bomber on its own did not compel the Z-95 to shoot at it rather than the ship.
But Valen was not heavy.
So, was the Z-95 allowed to shoot at the ship, or did it have to shoot at the TIE Bomber?
