"A-acting Sergeant Julianna Delgado, 23rd Regiment of the National Liberation Front. My squad had just taken prisoners, and then I was here. I have to go back, they need me over there."
Oh, you're so full of it. It was a big war, and you were just one little pawn on the board. Believe me, Delgado, nobody's going to miss you when you're gone. They'll get a new sergeant, and I'm sure he or she will do just fine.
