I'm not in the military but I grew up on and around Ft. Benning, GA as my grandfather was retired Air Force and worked civil service at Benning. One thing that strikes me as funny is that, though access has grown increasingly more controlled since 9/11 (with obvious reason), the gates are not better protected. 9 times out of 10 when I do have occasion to go on post, I never see MPs at the gates, I see contracted private officers or DoA police officers, who are invariably armed only with a pistol and generally there are only 2 or 3 of them on duty. Not to mention the fact that quite a few of them look like they could be taken by a 5 year old with a pellet gun.
Its too bad there isn't carry on federal installations. The government trusts our soldiers with automatic weapons and insanely expensive other munitions and equipment when they are overseas, but they aren't allowed to keep a personal weapon on duty back home. Really too bad the government fears those who are charged with protecting it.
