Hard core

This is the strategy followed by most of the armies that you'll find in online games: a core of heavy infantry, and cavalry and archers in lesser proportion, just enough to cover the ranged and flanks combats. It doesn't require much explanation, the standard construction are 3 units of archers, over 4 units of medium or heavy cavalry, a couple of units of spearmen, and the rest is spent in the infantry, which is the key piece of the army. Playing this way isn't so critical to avoid flankings as with other strategies, but it's still important.

Here you have the iceni army used in the video. The roman is the one that appears in the hammer and anvil section.
