What you see above is eight 24-figure single-battalion regiments. All are based on four-figure 40mm square bases. Generally these regiments will operate as 20-figure units since their stands of grenadiers (rear row) will be converged into separate units within their brigades.
Not pictured are also a pair of "irregulars" . . . also in six-stand 24-figure units. However they are based differently and have no grenadiers. The irregulars are based (as are mounted troops) on 50mm square bases . . . (okay I use 47mm square bases instead so that they'll fit in my display cabinet).
Instead of being based in the two rows of two like the regulars, the irregs are in a "diamond" pattern of 1-2-1 so that even in line they have an irregular look.
As I mentioned, mounted troops are based two to a base on the same size bases as the irregs:
Above you see four 12-figure units of Horse and four of Dragoons . . . I haven't yet decided whether or not to re-flag them.
Also not pictured are a couple of Hussar Regiments; and three 12-figure units of foot skirmishers which are mounted on pennies. In addition have a generous selection of Generals, Brigadiers and Aides-de-Camp . . . as well as Artillery, of course.
