Like the medieval knight Roland, sounding his horn as an alarm before sacrificing himself and being killed by infidels at Roncevalles.

Not exactly. Roland put himself in danger to save others, but he did not kill himself. The enemy did the killing.
But Roland died at the enemy's hand. The Church sees a difference between a military act certain to bring death to the hero, and a suicide. That was suicide. But then, again, his enemy is not exactly a fighting army, even though France, again, is suffering from a foreign invasion.
The times have changed since Roland the Furious, for the worse.
