Life is short and you die at the end of it. But everyone wants to have a sense of purpose for their life no matter how long or short that life is. There is no greater purpose than to have the courage to be a member of one's country's military and thus to stand in the gap to defend that country's way of life. Particularly in the USA God is with each soldier, sailor, air[wo]man, and all Americans should be respectful and humbled by the fact that fellow Americans are willing to stand in the gap for us, those they leave behind, in times of war and cold war.
