"No trooper, no special forces operative wants to sit behind a desk. We joined up to kick some doors ..." — Ant Middleton

When I left the military, I thought I would not have any problems with the transition - I'm very adaptable and very versatile - but I was wrong.

I joined the Marines, passed Special Forces selection, and became a young leader in the military.

When I was younger, if I got into arguments, I'd become aggressive and violent, but I learnt the hard way that was only going to end negatively.

I was point man, which meant I was the first through the door, hunting down Taliban commanders, knocking down forts every night.
