Question about Blast/Bombard.  Most snipers have the concealed ability thing where they can only be attacked at short range, but someone I was playing against claimed that if he attacked another unit in the same hex, (Say an M1 Garand was in the same hex as a the Hunting Sniper), he could attack the Garand with a Blast Bombard unit and the attack would hit the sniper. I was thinking this was a Can’t trumps Can, since the Sniper says it Can’t be hit, even if the other unit says it can. Any official ruling here?
