So for those who believe all suicide is the unforgivable sin... how does that square with those who throw themselves on a grenade to save the other members of a platoon in a war zone? Is this an “unforgivable” act?

She is not throwing herself on a grenade. Those that do know that they probably won’t live, but if they do or don’t others will be saved by their act. That is the ultimate sacrifice (Jesus anybody?).

They aren't throwing themselves on a grenade for the express purpose of killing themselves; they're doing it for the purpose of saving others.
