In the American TV series "Burn Notice", what was Sam Axe's former profession?

That show was one of my favorite series. Bruce Campbell was hilarious in it

Great series wish it would return.

Sam Axe was a former FBI agent, not a Covert Operative. There was a special episode that was all about Sam's rise and fall.

that was a great show. I love Jeffrey Donovan. I thought Bruce's character was great.

Never heard of the show.
