I think he's referring to the post that started this topic of a guy who got through indoc and then dropped 5-year mil leave orders. 5-year orders don't just find you, you have to go out and find them and volunteer to take them. I don't think anyone has any problems whith those who do his/her normal Reserve/Guard duty which sometimes includes long term orders, but this a little bit beyond that. So were they truthful during the interview when asked about availability and commitments? Maybe they were one of the long swimmers in the pool and something came up. I don't think we have the whole story.
Back to the thread topic. For mil and non-mil alike, don't like about your availability and commitments and you'll be fine. Also, for everyone, do yourself a favor and get through training and consolidation before taking long stretches away from Delta. It will work out better in the long run.
