Leadership and GS (in General)

Found some old threads where people didn't know and not in wiki. Does Leadership's boost to ST apply before or after Giant Strength? It seems to be a during-combat effect like an enchant, but it's also an armor feature and armor bonus/penalties come before GS applies in general. So wanted to be sure before buying one.

During Combat, after GS/GM.

You can see this when a Leadership minion dies, and you lose thier Leadership Bonus.

It won't boost STR given by GS.
