I love it! Another "I pilot, I only fly" debate! Brett and Gatordev are right on the mark. If you signed on for this job under the impression that all you were being trained to do was fly....dump your letter at the end of your shore tour or as soon as your commitment is up. The lessons learned and the expanded understanding you get from stepping outside your community bubble are vital to being able to go back and effectively do your job in a dh/xo/co role. In you JO tour you are learning leadership skills and learning to "fight" your platform. You level of understanding as to how your part in the puzzle fits into the greater strategy is pretty limited. By taking a tour on the boat, you get a better appreciation of the bigger picture, you learn how other platforms (ships, subs, helos, fighters, cods, vp, etc) fit in to the picture and the coordination required to execute the overall strategy of the battlegroup and the team as a whole. This information is important, because if you are fortunate enough to get back as a dh and beyond, you get into the realm of planning and execution and fighting the entire squadron....employing your assets as a whole to fulfill your part of the overall requirement. It's about having enough experience and knowledge base to make proper use of your assets. IT IS NOT A PENALTY FOR BEING AN AVIATOR!
Even on the self-interest side, if you want to go that route, the boat tour is a must. I can only speak for the VP side, but my understanding is that other communities are going to see more pain and suffering and lower screen numbers in the dh world as well. Don't bother with the "I know someone who" responses, as there are always exceptions, but if you elect to try and get by without doing a boat tour, it is a deal breaker on dh boards. Why should they pick someone with experience in only one arena when they can take someone with experience in all areas of the Navy battle force.
I am on my dis tour now. Did I necessarily want to do it? Did I think it was going to be as much fun as my fleet tour? No, but I knew that I would learn something, and I would be better qualified and more effective in my job should I get to go back for a dh tour. Stop ?!@#$ing. If you don't want to do it, don't, but accept the consequences.
