how to give a specific promotion to *all* units?

[yourmatthew999]

'nother question
how do i assign one specific promotion to be given to *all* units
or at least a certain group of units ~ in vanilla bts
is it possible with xml?
i know i can assign the *availability* of a certain promotion,
but i am trying to have some factor suddenly give just about all units
and after an added "training" and/or "discipline" promotion.

eureka it worked!! : D
i just found one way (won't tell you what the popup message to myself said. 'hey ******e it worked!'
and that was through 'events'. as much as i mod, i've never used an event before.
it gives 'training' to all my melee units now.
how does this sound, a mod where the events basically randomly determine a lot of the game.
it will choose maybe 2 or 3 civilizations who get advanced military discipline and training
(see: the roman empire, possibly egyptian, greek phalanx)
next it can choose who has exceptional brute barbarian power (no offense but the early germans, celts, vikings) or even one of a kind permanant 'berserker' giveaway to one lucky
civ.
then later on it can choose who gets a huge military of panzer tanks etc
only problem you won't know it if a civ you don't know yet gets it, and you have to keep
