Taypo,
Every single Service Member goes through firearms training, except for Chaplains (but some of those guys can really shoot). It does not matter the branch of service. Some get more than others (Marines, combat arms etc) and some get less (Air Force, Research Officers). They all have proven their competency with firearms.
What I think you are trying to get at, is that you think that they are going to become a liability to anything firearm related. With that being said, how about those states that do not require proof of training (WA, PA), or those that allow unlicensed open or concealed carry (AZ, AK, WA (open) etc)? Many of those people in those states have far less training than a slick sleeve Airman, with less common sense than that 18 year old Infantryman. And they carry!
Or, better yet, how about the stories of cops and Feds that incurred a case of Glock Leg, or those NYPD cops that shot 16 rounds, and hit 9 bystanders? (Links below) They have had extensive pistol training and they are also armed professionals. What is the difference though?
The difference is that we are trained to "support and defend" through superior firepower. And we are the disArmed Forces of the United States of America when it comes to any form of terrorist attack on our own soil. Before Chattanooga, there have been many other attempts at attacking military installations. Fort Dix NJ, Fort Hood TX, Fort Bliss TX and Norfolk VA all have had terrorists attempt an attack and 2 of them succeeded. These are just the attacks off of the top of my head. I was nearby at one of these. It was not pretty and I know I am not alone when it comes to pushing some boundaries to ensure the safety of those around me.
If you are allowed to carry in your home, your neighborhood, your place of work, your grocery store, and your "big box store", why are we not? Especially when it has been proven many times over that we (the Military) are (relatively) soft targets for any form of attack? Yes, we may have armed guards at the gates. Would you still carry in a community where you had controlled access and armed cops minding the gates? And the response time on many installations is comparable to the times off post. And this does not even cover recruiting stations, National Guard Depots or any other place that is not a major installation. ALL of which have far less security than post does. I do not just want the military to carry, I would like some form of National Reciprocity, but there are times where we (as a firearms community) must take that small step before we can take the big one. I will personally be ecstatic if I am allowed to lawfully defend myself and my family next time an attack happens. Not if, but when.
As a side not, to me it sounds like you are being an elitist about Texas, and have some misconceptions. If I have misinterpreted, please enlighten us.

P.S. We get and give use of force, laws and regulations about firearms (open and concealed, civilian and military) very 6 months or so. And I am not SF, MP or any other MOS that gets to carry concealed daily. And allowing us to carry will actually be cheaper (lives and $) when the next event occurs and everyone is reacting and dying.
