I can think of one troop that is better than drafting Churchill's redcoats
Redcoats are certainly wonderful drafting material. But in Warlords I think that it is arguable that Toku's riflemen are just as good when drafted and sometimes better. Assuming that Theocracy is run so that draftees get 2 exp we get:
Both units have Protective giving free drill1 and free CG1
The redcoat gets its UU bonus of 25% V gunpowder (equivalent to pinch)
The Toku rifle gets free combat1.
With 2 exp the redcoat would normally take either combat1 (for offensive use) or CG2 (for defensive). Meanwhile the Toku rifle would take Pinch or combat2 (depending on enemy troops) or CG2. There are pros and cons but I prefer the Toku draftee in most cases both on offence and defence.
This is even more telling later in the game if the drafted troop gets upgraded when the readcoat loses its UU bonus but Toku's rifle doesn't. However this advantage is purely for drafting, redcoats do have other advantages, for instance if you upgrade drill4 longbows to redcoats they are better than Toku's equivalent.
