Rescue wings, if they fly helos, have a number of enlisted crew positions. I flew a couple of times with a reserve unit in an HH-60, and got to be the door gunner at night with NVG's, along with a PJ insertion done at night and a refueling in complete darkness. It was a blast.
Traveling two hours for a drill weekend is not out of the ordinary. Part of the deal is that you would get billeting on Friday before drill, and Saturday of the drill weekend. It does mean more time away from other activities and interests, along with the costs of travel, which typically are not reimbursable.
With the current ops tempo, you could be asked to deploy for 60, 90, or 180 days at a time. As a member of the flying crew, this would be an expectation.
If you make it into an aircrew position and successfully accomplish the training, and if you do a good job, then you might do well on a pilot board, and if there were openings, you could possibly attend flight screening and training. Helo time, like time in single engine fighters, is factored somehow toward total multi engine hours for airline jobs. While heavy pilots can accrue thousands of hours in a few years, fighter pilots and helo pilots build hours at a much slower rate.
There are a lot of "ifs" in what I just said, so if you want to get into the majors, there are a lot easier ways. If you want to serve in the military, with all of the responsibilities as well as the fun stuff, than this should be your goal, not building hours toward something else. You and your supervisors ultimately would not be happy if you were planning on solely using an enlistment in the military as a stepping stone toward flying with the majors, at least in my opinion. Participation in the ANG takes a lot of time and commitment, and certainly a lot more than the weekend a month that many people think. This is particularly true as you advance in rank, or if you are in a flying position, where currency of training is hard to maintain.
I think I put in over forty days last year, not including the weekend drills. This also did cover several training courses as well as a short deployment. So, if you want to be a member of the Guard, you should know the responsibilities, both in terms of time and commitment, so you are ultimately not unhappy.
I would never trade the experience for anything, but it's not for everyone.
