stat_health 1, 3 (used for heavy)
stat_health 1, 2 (used for light)
As above I see that cavalry has a separate number of hit points (the second figure), more for Heavy cavalry than for Light.
The EDU says:
; stat_health Hit points of man, followed by hit points of mount or attached animal (if applicable)
; Ridden horses and camels do not have separate hit points
So does this mean that the first value goes unused if the unit in question is cavalry?
Presumably it also means that a light cav unit with exactly the same armour, attack etc as a heavy cav unit will die quicker. So does this extra hitpoint somehow represent horse size/strength?
