I’d like to standardise the base size across the units on the game.

Currently this is set to 40mm wide but no specified depth. I’ve been using 40mm X 30mm with two dice holders to show the formation and number of combat dice.

An example of the current basing on tabletop simulator

I’m now considering making all bases sizes 40mm square. There are two reasons for this;

1) it will allow players a little more room to make diorama bases.

2) if the player feels inclined, instead of using a die to denote the formation they could make three different base styles up for column, line and square.

The benefit to this is that it would also give the battlefield a more realistic look.
