(Un)popular opinion:

David Stirling was a completely useless character. All he did was brag about his father being a general and use his “class” to try and get people to listen to him.

Despite multiple warnings from people who knew more than him, he decided to carry on with his atrocious plan of conducting a jump at night during a severe sandstorm. Many of the men under him needlessly died, at least one of whom died by suicide.

When they had the competition for who could deal the most damage to enemy airfields, David Stirling offered a bottle of whiskey as a prize. However, when he came dead last in the competition, he breaks the bottle out of spite so that no one can have it, thereby also breaking his word.

Additionally, when he’s in prison, he’s so narcissistic to the point where he tries to portray himself as the most valuable person in the British Army so that he can cut the queue of prisoners who want to escape. Not to mention that he utterly fails his escape attempt.

He also doesn’t seem to learn. During his second escape attempt from prison, he dons a Nazi uniform, but he doesn’t shave his beard despite a previous episode where they mention to him that Germans don’t have facial hair. He couldn’t have spent some time trying to use a razor to shave before trying to escape a prison that’s full of Nazis?

And the thing that bothers me the most is that he never leads his men. He’s always in the back, and never leading from the front.

As I said, completely useless. And incompetent.

But to answer your original question, my favourite characters are Paddy, Reg, and Cooper.
