I had a Priest, who as an Ordained Deacon, served as a medic in WWII, doing medic things and giving comfort where he could.
When the aid station he was working at was overrun by infiltrators, who started to shoot the wounded and the medical staff, wearing Red Cross arm bands, he picked up a weapon and killed the enemy who were attacking his patients.
I learned this story when I entered his study, in the Manse, for help with my French lessons and found him cleaning a captured pistol.
He said he carried it, concealed, for the rest of the war. Just in case.
I guess you might consider him a Warrior Priest.
