Assault frustration

[Blackcloud6]

I just finished the first scenario from Invasion 44 and my usually frustration with "take the town" scenarios came up again.  Turn and after turn of assaults against the town hexes and the entrenchment hex did nothing.  I get the Germans either disrupted or even demoralized in the hex but by begin 8 morale troops with good leaders they simply recover and the process starts all over again.   Turns of nothing but die rolling make for little fun.  This is about how 99% of scenarios I play with high morel defenders in towns go.  The attackers never win.

So how are these 8 morale ubermensch beaten in towns and entrenchments?  Can someone show a turn by turn tactic that actually works?

Frankly, I'm about to pitch PG because of this and move on to something else like Nations at War or go back to Panzer Leader because I perceive the assault is a severely broken mechanic that greatly affects most of the scenarios.
