I played the Operation "Santa Maria Infante" as the Americans vs. a friend and encountered a concrete MG pillbox on S Ridge that was hardened like NORAD at Cheyenne Mountain. I could not take the pillbox out with the following:
24 shots from bazookas at the rear door, point blank range. The MG in the pillbox killed one bazooka team at the rear door, the other two teams survived.
6 Assaults from two full strength infantry squads failed from the rear door. One squad ran through the rear door and out the slit and was routed, one squad was inside the pillbox and was eliminated by the MG. The routed squad was subsequently eliminated by the MG. Another squad attempted to take out the pillbox from the front quarter out of the firing arc of the MG at close range with no damage inflicted.
Several point blank 75mm rounds from an M10 at the rear door failed to damage the pillbox. At that point I gave up trying to take the pillbox out.
I had half a company of infantry and 3M 10s at the objective flag by that pillbox but could not get the VP for that flag as it stayed at ? as long as the pillbox was viable.
The point to this rather lengthy description is to put up for discussion the difficulty or strategies used for taking out the pillboxes. It would seem the only thing that was effective for me was a point blank shot at the slit by a Sherman on the pillbox on the Tits. I had 4 concrete pillboxes taken out in CMBB by 20mm from armored cars at over 800m in one or two shots.
Please share your strategies or comments on whether the pillboxes are given too much strength. Thank you.
