Card text says you may sacrifice a Soldier/Warrior unit to prevent damage, this does not forbid you from sacrificing Straken as he's a Soldier Warlord unit... my question is, does he become Bloodied if Hale? Or does he die altogether?

RRG Sacrifice section, "A warlord unit cannot be sacrificed."

Thanks.

I have a slightly different but related question. Can an eligible attacked unit who is about to be damaged sacrifice itself to Glorious Intervention? It seem like this works according to the rules, but it seems a bit weird (that a unit is sacrificing itself to prevent damage to itself). The net gain of this use of the card would be that the target unit would deal damage back to the attacker.

The attacked unit would of course be killed in the end, but can I use the Glorious Intervention in this manner?

Can't see any reason why not. Thematically just think of it as the unit going all-or-nothing into a counterattack, with no thought as to their own defense

Yeah, not seeing anything that would stop you given that it says "sacrifice a Soldier or Warrior at that same planet", doesn't state another Soldier or Warrior, so technically a legal play given the damaged unit is still a valid target for sacrifice much in the same way as Flamers sacrificing as a response to being assigned lethal damage.

Glorious Intervention works for the "you can't fire me; I quit" sacrifice because Reactions to assigning damage are played before damage is actually placed on the card. But you have to pay attention to the timing of the effect because this will not be true for all sacrifice effects.

attack is different from dealing damage am i right? so such abilities cannot be reacted with glorious intervention?

Yep, it even states it on the Glorious Intervention card.

Well, I'm anal so I have to harp on the terminology. An attack is a specific way of dealing damage. The process of dealing damage (assign-shield-place) is not different for an attack. It's just that one ("dealing damage") is a general term and the other ("dealing damage by an attack") is a specific example of the general process.

Keffisch is correct, though, that the wording of Glorious Intervention only lets you use it in the specific circumstances of an attack, though -- not in response to any, general effect that deals damage.

Glorious Intervention works for the "you can't fire me; I quit" sacrifice...

This is a hilarious way to talk about timing (and helpful!).
