Normandy LCT Rockets are useless against bunkers

[Liebchen]

I don't understand why these rockets, with an AT factor of 80, cannot cause a single casualty or disruption against the bunkers in Normandy '44.

IIRC, those landing craft rockets were historically not very accurate.
In game terms are you taking into consideration that BUNKERS are -20% defense. The best target terrain would be clear terrain.
Check the pdt. There is a range fire modifier also becuse these are direct fire units not indirect fire.
The best range these fixed place units can get is three hexes. That is another -20% for a 40% attack strength reduction at best. Other BUNKERS in better defensive terrain lower the attack strength even more. PILLBOXES defend even better.
 
I ran a couple of shits in the Omaha scenario to test. Must have better luck than you? I targeted a BUNKER in a clear hex.

It all begs the question: Why have them, at all?
