Yes and he was and is a very brave man. However, he is not in the direct line to become king of England.
He was and is still in the direct line.
At the time of the Falkland War, he was in the same position Harry is in now - he was second in the line of succession. Right now, he’s fourth.
It’s Charles, then William, then any of William’s (hypothetical) children, then Harry, then Andrew.
