Creating Troops

[Wraithcannon]

Has there been any work on a set of rules to generate creatures with the "Troop" subtype using different small or medium sized creatures as the base?

I wanted to generate a troop of Charau-ka but have no idea on how to go about doing that.

Try this, there is the Troop subtype but has no offical rules, this is 3.5 stuff but has rules.
