To add a bit of interest to the battle groups I have included some figures from command packs to act as centurions and signifers on some of the bases.
I believe historically the centurion was positioned on the front right of his century. This will be illustrated by the placement of a centurion figure on the right and a signifer on the left position of a base. Once formed up into a battle group it should appear as if the signifer is in the centre of the rank with the centurion on the front right of a battle group. Hopefully this will add a touch of interest to the massed ranks of legions.
