 I don't think there's a lot of difference. We approach things in very much a similar way. Marines are very kind of professional, they're all about getting the mission done and there's a similar sense of humour there as well. I really enjoy working with the Marines. More and more we tend to find that we're operating with fellow NATO forces when we're away in conflict areas around the world. This just helps us to ensure that we're both operating to a similar sort of level. Any training that we can do before we actually go and do it for real is obviously very important. It mitigates the risk to the troops that we're flying in the aircraft and it means that we can actually achieve the effects that we want more effectively and more efficiently. I saw the crew chiefs for a little bit of a visit. Some of the similarities came out during that. I think that people have a similar sort of mindset in terms of this organisation is very professional, they're very dedicated to get the job done just as we are in the Royal Air Force. They look to each other to get the job done. It's not a single process as in I need to achieve X, Y and Z myself, it's a team effort that runs both through the US Marine Corps and the Royal Air Force.
