"Basing Cossacks" Topic

I have started building a Russian force for the later Napoleonic campaigns. Basing regular forces is straightforward, but what about irregulars such as Cossacks?

I use General de Brigade and Black Powder as rules with 28mm figures. Currently my regular cavalry is mounted on threes on bases 60mm frontage x 50 mm depth. Thus each base is roughly a troop/company.

What do people advise for Cossacks? All on single bases? Bases of varying sizes? Different numbers on a regular base? I would be grateful for advice on how to represent the Cossacks fluid formations.

50x50 two staggered?

For Black Powder I base my Cossacks on 50 X 50 bases 2 figs per base (28mm) which is how I base all my cavalry including irregulars – usual unit size 6 bases; I try to use a variety of poses/painting to make them look less "regular" than, say, a unit of dragoons

Stagger the figures and go for different poses and you'll have a nice looking irregular band.

The non levée ones are not so irregular, but part timers. They fight regularly in a different way than the "regular" cavalry.
Their march columns shoukd be roughly the same.
At that level of possible realistic tactical finesse, you coukd have them with spreading out a bit the stands to give them less punch directly and more envelopping powers, together with the ability ( but chancy if too close) to evade.
Their Lava tactic is all about this.

In BP & GdB I allow a thin skirmish line of Cossacks to interfer with the command distances.Command distances have to be measured around the skirmish screen. They also evade 2" further than light cavalry with a 2 pip advantage.
