Regiments of Foot
I decided on wings of 8 musketeers, which handily is a pack; a pike block of 12 pikemen (1 1/2 packs); command strip of 4 (1/2 pack), and a couple of halberdiers (1/4 pack). So a regiment was 4 1/4 packs or 34 individuals.
Basing - rather than base for a particular ruleset (not important if I am providing both armies) led to the following idea. Base figures on 15mm × 40mm. This would suit strips of 4 figures, with halberdiers based 1 per 15×40. A couple of blank bases would make everything neat and tidy for a 120mm × 60mm movement tray. This would also give the option of having the command strip at the front or at the back once the roughtie toughtie stuff starts.
Here's a couple of views of Colonel Charles Fairfax’s Regiment of Foot to illustrate my infantry organisation. Pretty pleased with how they have come out.
Currently each side has six regiments of foot, with another three in the pipeline. They also have a regiment of firelocks coming too.
