Hi!
I'm just beginning to tinker around with NCP so i'm here mostly to listen, not to speak
The question is a good one indeed.
The problem is that my experience with AACW is not too usefull here as the ACW cavalry is very different form the NCP one.
Different stats, different uses... on ACW there is no cavalry charge system nor there are squares. Basically,the ACW cav is not too good to use on big battles.
Is just like fast but weak infantry
On ACW i use cavalry as
1 - fast raiders evading combat and destroying what rails and depots they can get.
2 - As in deep scouts to check what the enemy is doing, again with evade combat orders.
3 - Medium sized cavalry stacks are used to defend my territory against enemy raiding cavalry, doing search&destroy missions.
4 - On secondary fronts with not too much force density and plenty of space to run around (the west and transmississippi mainly) i form cavalry divisions with horse guns as fast moving combat troops. They are weaker than infantry divisions but can get somewhere pretty fast and defeat small forces or second rate units (militias, garrisons).
5- On all my infantry divisions i like to have a cav regiment for their spotting bonus.
Now, on NCP game, some of these missions are no useful at all (rails blowing?)... other should be useful still (some limited raiding, scouting, fast divisions to use against weak units, for example militias and irregulars on the Peninsular War...)
But i suppose now cavalry should be pretty useful in real big battles, but don't know if mixed or on independent stacks.
Also it would be good to hear for some tips about the sue of different kind of cavalry: heavy, light, capable of firing like dragoons...
Regards
