panzer campaigns - bunkers

[CheerfullyInsane]

As CheerfullyInsane said "The combination of anemic Hard Attack values, no Trench hex, and a 200% beach TEM almost ensures that Omaha will have to be rescued from outside."

So a quick and easy change is to dial the TEM of beaches down to 100% and see how that plays.

Reducing the TEM helps, but it's not enough with Alt. Assault on.
Even if most of the US units stay undisrupted (and that's a mighty big 'if'), there simply isn't enough Hard Attack units available to assault off the beach.

Personally, I refuse to play with Alt. Assault on.
I get the idea behind it, but it brings all sorts of weird situations encouraging ahistorical play.

In Normandy'44 you're better off parking a unit of StuGIIIs in a bocage hex than infantry.
Granted, they'll have Combined Arms penalties, but unless the Allies bring armor/AT-guns of their own, they can beat back any infantry assault on their own.
Unsupported armored units holding back infantry in bocage-country......right.

In Japan'45 you get no use out of flame-tanks, unless you're attacking trenches.
If the Japanese are in bunkers, the tanks attack with their 37mm guns instead.
It's completely bonkers.

If an optional rule encourages you to lead a seaborne assault with AT-guns, something is seriously wrong.
