I disagree that the cost is more and the return isn't worth it for civilians and contractors, to a point. My billet is charged to the gov't at say $200K/yr. Most of that is overhead costs for a desk, computer, phone, plus the company overhead for people that aren't directly on the contract; payroll, contractsl/egal, and upper management. So if you look at it its actually three-four paychecks per contract man-year. Now you're on the same pay level as a mid-career E-5, but he would also be getting housing, possible education payouts, and health care. We're doing basically the same job but he's being pulled off for military training, retirement ceremonies, guard duty, and all the other piddly BS all Services task people with outside their regular job. I am only tasked with fixing stuff and not a whole lot else. I have to pay into my retirement and health care. My house and utilities aren't paid for (although Service memebers on bases in HI are starting to get utility bills). Are there civilains and contactors that are "less than stellar" performers that could really use to be sent to somewhere else, sure. Like I said before there are a lot of jobs that military members cannot and should not be responsible for. I don't think it is a good use of taxpayer dollars to send a Service member to handle Foriegn Military Sales, Contract/Financial Management, and Depot level work. They are better utilized at the unit level. There is also something to be said for contiuity. Every two-four years all of the "corprate knowledge" of a command has turned over and has to be retaught. The civilian personnel, here at least may move around a little but there is always a direct line to "that guy" that designed/built it first.
Should contractors or civilians be taking overseas billets or large portions of the Shore/stateside billets mid-career, junior Service members could fill, no. Johny Blackwater has no reason to be in Iraq/Afghanistan instead of Joe Grunt. The whole reason companies like that exhist is we've cut our forces to the point they can't get the job done on their own. A lot of the mid-career members that are leaving would have left anyway, they just have a more compelling reason since they can be a contractor. They quickly find out that the 2-3 times the pay really isn't that much take-home after taxes, benefits and living expenses are factored in. My pay today is double my base pay as an E-6 ten years ago, but the actual in-the-bank paycheck is only $500 more a month.
