I'm mindful of the El Cid range soon to come out from Hat but there are a couple of Crusade things we need to flesh out the armies. 1) Muslim horse archers - only 4 in your Seljuk Turkish cavalry is a real problem as when I was working out an army I wanted archers at a ratio of about 3 or 4 to 1 heavy cavalry. 2) Crossbowmen, again other people are on this but, they are one of the most distinctive features of a late Crusades,Christian army, and should have been there from the start
