Just as ALL male member of the RF have been in the military, for generations ( it’s required of them! ), so was Harry, who did NOT do anything “wonderful” at all, but was cossetted and guarded by a team of SECURITY, the entire time he was in, and not allowed to be anywhere even remotely near the front lines/in battle.
Actually, I figured that was probably true. I always wondered how much they surrounded him and hand-picked his missions. Same with his brother. His brother claimed to dodge Exocets (by climbing vertically in the helo).
