As others have said, there are numerous ways to serve, the D.O.D. has more than a few places for folks who wish to support the frontline. Too often forgoten in the glare of military as fighting force, is the simple idea of service to others, which the military is wholly a part of. The ideal of a republic is that the military serves and defends, and however much our own may fail, through their own faults or from those whom they serve, we can hope and insist through our contributions that they still strive for a greater good. There is much any and all can do to serve, even if you can not wear a uniform.
