Roundhammer 1943 US Campaign (Spoilers)

[duff]

A question re the 2nd battle.
I found about 3/4 of my vehicles got bogged crossing the mud. They then got pounded by artillery for the rest of the battle causing heavy casualties among my open topped halftracks, M10s and assorted light vehicles. Is this intended to create the experiance of being the wrong force for the job (mechanized force landing on mud), is it intended to be played with breakdowns turned off or am I doing something fundamentally wrong?

I eventually got what I considered acceptable casualties using paratroops dropped in behind (with a couple of glider light tanks) and sea landing of infantry and a few halftracks while wasting some landing craft evacuating my armor off the map entierly. Not sure that's in the spirit intended however!
