the petard was a heavy cannon thing its only a suicide bomber in AOE the horse artillery should be normal artillery that deploys when stopped, I don't think musketeers were used in the 18th to 19th centuries, the gatling gun was invented rather late, thats why I suggested the puckle gun which was invented sooner then the gatling gun by 150 years, I agree with the field hospital, I think the falconet was a light infantry dragged cannon with medium range would not have to deploy to fire, the longbow and crossbow were out of service in the 18th to 19th century period this seems to be in, the hussar is light cavalry but is a cooler name, don't know about the bank, envoy's a good idea but the dumb ai might send them to attack or make hordes of them for nothing, the ruyter sounds ok, skirmisher sounds good but thats kind of what Rogers rangers were, guerilla fighters, mortar, sounds good, I don't think there should be the church priest or halberdier as the church and priest were not used in warfare and the halberdiers old fashioned, the heavy cannon sounds great, it could have a requirement that it has to morph to deployed mod to shoot, cuirrasier could be medium fast cavalry, but a lancer could be included and could be faster and have lighter armor, the dragoon sounds great it could have a sabre for melee though, there could be a bombard as an improved even heavier mortar
