What I'm going to write will undoubtedly upset some of you. Let me start by reminding you that I am an Army veteran. I served when called, and I love my country. However, as the saying goes, I do fear my government, because it has become a government of professional politicians and wealthy insiders, rather than the government "of the people and by the people" that was intended by the framers of the Constitution.
There are three levels of military service currently available: The regular services (Army, Navy, Air Force, and Marines -- and Coast Guard in time of war); the active reserves; and the national guard. Since Vietnam, the "gummint" has made a decision to reduce the overall size of the regular (full-time) forces. While this would appear to be in accordance with the ideals of the Founding Fathers (who did not think the government should have any standing army at all), it is a sham.
Why? Because Washington still wants to have the "benefits" of a standing army, without having a standing army. Read the recruiting information from any branch of the services, and all you'll see is a lot of fluff about how they'll give you an education, they'll teach you valable skills, yada yada. They all bend over backwards to avoid any discussion of the fact that enlistees are soldiers, who may at any moment be sent to some unlikely place to get shot at.
There have actually been a small number of desertions and AWOLS by service personnel who felt they had been deceived by the military when they enlisted. And there are huge numbers of National Guard who feel that they should not be where they are. They are probably correct. The National Guard is supposed to be the third and lowest tier in the hierarchy. Except in time of war or emergency, the National Guard belongs to the individual states. It seemingly makes no sense at all that we have federalized National Guard units and sent them to Mesopotamia when there are active reserve units still in this country. The reason is that the reserve units aren't the type of units they need in Mesopotamia, so they reached out to the Guard units to take up the slack.
What this means is that (a) the regular services and active reserves are under strength for the purposes the gummint needs ("wants") them for, and (b) there's nobody here at home guarding home base.
No matter how one looks at it, it isn't right, and it isn't smart -- but it is political.
Fire when ready, Gridley.
