Strategy - Advancing against very strong AT Guns

[GeneSteeler]

I've just set up for a solo game of Grossdeutschland 1946. (Hypothetical - Scenario 8, check it out!). The Germans are just about to enter from the north.

The situation is that the British are set up on a 40m hill dug-in and in entrenchments. They have lined the edge of the hill with infantry with some very effective (8-8) AT Guns behind them.

Germans are to take the hill. They have loads of infantry in APCs and some Panther IIs. The APCs don't have a chance against the 5 Br AT Guns. Starting turn 5 the British armour (Centurions) may appear. It will take them probabaly 2 turns to get up the hill.

Germans have decent OBA (55 and 42). British OBA is more modest.

How should the Germans advance?
Advance on foot? In APCs? Wait for the Br AT Guns to get spotted then OBA the snot out of them?

Panthers lead the charge? They will get "stalled" by the infantry and the Br AT Guns will get some pot shots on them.

I think it is important to get on to the hill as quickly as possible because if the Centurians set up camp there, it will get very nasty indeed.

What are your thoughts?
