The deployment schedule is typically much different than standard.  Usually it will be two weeks here, 4 weeks there.  For a standard 7 month dep they will send out a crew for half of it and then send out another crew to relieve after 3-4 months.  There is always a chance for an individual billet oversea however.  They seem to be getting more popular.  For example, they have sent guys over for 6 months to stand up iraqi squadrons and oversee the training the setup of new bases. Those typically requie TS clearance which can be helpful in the future.
