I think traditionally tabletop wargames rules have tended to define troop differences in terms of their equipment, and this leads to a temptation to separate troop types from units which may have had mixed equipment. There are medieval rules that split medieval ‘lance’ units into separate units of knights and sergeants. A lot of ‘dark age’ armies have whole units of ‘nobles’ with heavier armour than the ordinary warriors. I suspect this isn’t a very realistic way of portraying these armies.
Board games are worth a look for new ideas, I think. In the near future I’m going to try the GMT ‘Men of Iron’ game ‘Infidel’ for tabletop Crusades battles.
