If you decide to enlist, it should be an intensely personal decision. A person can have a lot of different motivations for it. Once on active duty you typically have very little choice about the nature of your service other than choosing from a variety of jobs based on your assumed ability. I thank Thomas Young for his service, and I hope for a peaceful end to his bitterness and suffering.
Oh, thou clear spirit, of thy fire thou madest me, and like a true child of fire, I breathe it back to thee.
