During act 5, scene 2, the Scottish and English armies join forces to prepare for the battle with Macbeth. I imagine that these armies will stand in a formation similar to the one above. The formations show the professionalism of the two nations and their intense preparation for this plan. Also, both of the armies will have flags that represent each nation to intimidate Macbeth into thinking he is being swarmed in every direction.
