I try to get a unit of Pikes and a unit of Musketeers to work grouped together. That way pike protects shot which is how it worked.

In the English Civil war the predominant formation was Swedish with Dutch coming from those Officers who had seen service on the continent. It has to be remembered that Pike and shot were formed in the same regiment. In the New Model Army it was 2 musketeers to one Pikemen and this ratio fell more to shot later on. Early in the ECW half a regiment was shot the other pikes especially for the Royalist side.

Unfortunately we cannot get integrated pike and shot but I find grouping a shot and pike unit together works well.

The Dragoons were mounted Infantry then, on inferior horses but Colonel Oakey at the Battle of Naseby lined his Dragoons along the Selby Hedges where they poured shot into the side of the Royalist cavalry as they advance and then toward the end of the battle he mounted his dragoons and succesfully charged the Royalist centre!

I try to use my dragoons behind hedges or at the edge of woodland, maybe securing a village or bridge pulling them back before contact. Dragoons are nuisance value unlike Col. Oakey I never commit them to close combat!
