"All spear-armed Saxon troops in the army should be armed with the same type of spear"
Does this mean
a) ALL Saxon units in the whole force, Thegns & Fyrds, must all have either spears OR throwing spears
b) all models in one Unit must have the same spear, but one could have e.g. one unit of Thegns with spears and another with throwing spears
Do javelins count into this rule? Does this include cavalry?
