Are we to believe Brando was worth exchanging for a major spy?

Okay...it is clear he stole a lot of "funds", but unless the British were going to send that money with him, why would he be worth exchanging a spy over? I mean wouldn't the Bundeswehr prefer someone who was of intrinsic value like a good fighter, or agent, or general of theirs? Brando's character just wouldn't be worth all that at that point in the game.
