Hi,
For my army, I use bases that comply with the ones used by players in the club I have joined. They had been playing Napoleons Battles for some 20 years before migrating to Black Powder, then onto Lasalle. However, I started with Blucher for Corps/army sized battles and have now started Lasalle. I did not want to have 2 separate armies, so I didnt use the 'recommended' sized units of 8 figures on a 40mm frontage, but 4 figures on a 20mmx25mm frontage, in units of 4 to make a battalion. This allows me to do all the formation changes. For cavalry, I have 40mm frontage with 3 figures per stand and 2 or 3 stands per regiment. I have also had sabots made so I can fit my Lasalle based units into a brigade sabot for Blucher allowing me to play a variety of games.
The bases are 3mm MDF.
It works for me
Basil
