You don't say what Danish your thinking of building 1690's or later e.g. Marlburian allies.
I would say Brigades of 4 infantry battalions (each of 18 figures) this gives you 72 figures in a infantry brigade.Two brigades gives you 144 infantry figures.
In this period there should be a cavalry figure for every two infantrymen, so this gives you 72 cavalrymen, which equals 12 squadrons of 6 cavalry.
I'd totally agree with your artillery one light gun per infantry brigade and one field gun with three crew.
As for generals, one C-in-C, two infantry brigadier generals and two cavalry brigadier generals.
Converged Grenadier hmmm not sure
research the army first if such units exist then go for it.
I'm building Marlborough's British army at Blenhiem 14 infantry btns in three brigades and 17 cavalry squadrons again in three brigades.
Hope this is of some help........Ray.
