[Shovah32]

My personal advice? Have several blocks of shield infantry at the front set to either attack (no ranged) or hold and attack (if you main offensive is ranged). Arrange them in a line with several gaps between them, between these gaps and slightly back place some un shielded (either 2 handed like flail/battle axe or dual weilding) infantry with the same command as the shielded units. This was the shielded units take the majority of attacks from charges (attack rear cavalry cant get past their wide line), missiles and magic and the first or second turn after they get stuck into combat the heavy hitters full up the gaps in your line, hopefully breaking the enemy (cavalry with lances, although not infantry can also fill this roll when place slightly further back)
