Thanks but that goes against what the latest PDF says about bunkers
and I quote from the new PDF
Bunker Option 1:
Defense: 3 (D6), 5 (D12), 11 (D20)
Transport Class: N/A
Bunkers are strictly defensive units. They can be built in any territory that has been
controlled for one full round. These units only protect a single border, which must be specified
when placed. Bunkers do not take damage and cannot be taken as casualties. If a territory
containing a bunker is captured, the bunker is destroyed and removed from play.
When defending bunkers receive 2 defensive rolls during the first cycle of combat only.
Bunkers also grant defensive bonuses to all infantry defending the same territory giving them a
+1 (D6), +2 (D12), +3 (D20) to all defensive values for the first cycle of combat.
