David and Cesary,
Sorry for the delay in answering your posts.
Real life+Problems with Internet+need to find good examples+natural lazyness=delay.
First of all let's specify what are we talking about. And here one needs to understand the idea of H&R oob. The basic organisation unit for cavalry and infantry is regiment. It consists of regimental commander and several units. These units are called EFFECTIVE batallions and squadrons as opposed to historical batallions in squadrons. Why the difference? Because due to the structure of game engine the size of the unit plays a very significant role and is not correctly taken into account. For example batallions 1200 men strong may be deployed in one hex which is nonsense. Plus there are several more aspects dealing primarily with morale.
So each of the regiments consists of a certain number of Effective units. their strength depends on the unit type. 400-450 for all the infantry, 150 - heavy cavalry, 130 - dragoons, 110-120 light cavalry, 100 - landwerh and cavalerie de marche, 85-90 cossacks. With a strict limitation on number of men AND UNITS within a hex it very much limits battle capabilities of the units. And very much diffirentiates the cavalry by types. So that Heavies are much more effective in charging enemy infantry while lights are more effective in screening etc.
Along with the morale, i.e. a measure how likely the unit is to get routed if hit hard, important role plays units ability to rally and undisorder. This is governed by regimental (and higher level) leaders leadership and command skills. For usual unit regimental commanders will not give a bonus to rally. And undisordering probability for an undetached unit will be about 30-60%. Depending on how good was the regiment, is it detached or not etc.
In this setting cossacks have several special characteristics:
1. They rout easily - they have effective quality rating of D, opposed to average C for all the other units.
2. They rally easily - regimental commanders have leadership B. Something no other leaders have. Normally, being stacked with leader, they will rally the next turn.
3. They undisorder easily - regimental commanders have Command B, something no one else has. Normally, being stacked with leader, they will undisorder the next turn.
4. As a result of 2 and 3 they are able to act independently, cross streams, woods etc. fearing not of getting disordered. Those who played big games know that is your cavalry patrol becomes disordered it's lost. This is not true with cossacks now.
5. Due to the small size of the units they can be successful only against weak enemy - fatigued, with high loses, single units that may be struck into flank etc.
6. If weather allows they are able to cross rivers (have Has boats status).
All this is already taken into account and can be verified with numerous examples of microhistory. The question is should they be given cossacks status or not. To remind you, it means that charge factor is not applied to them, unless they attack routed infantry. To understand that we need to look at the actions fought. Were there examples of successful charges of cossacks vs infantry? Were there cases when infantry threated with cossacks charge formed squares? If yes, we should not mark them with such a status. If no, we should.
The point of fact is that there are such cases. The facts soon to follow. Stay tuned!
