It is fun to play with all the shiny best kit but I'm in the realism school of thought. To have any real chance of sucess even against the AI you need a balanced force. Big Tanks with massive guns and armour will still get creamed by trained infantry if in urban areas and forest.
Donīt take them into forests and towns..
Thatīs what the grunts are for, maybe a Tiger 500-800meters behind the main grunt line ina town, closing the road from enemy vehicles..?
And PatG, I hate enemy snipers, and they canīt still do good things like close assault effectively and keep positions in 1 hex range.
