For my fellow olds, Fort Moore used to be Fort Benning, and if American Cold War adventurism is often questionable in motive and frequently despicable in practice, at least Moore didn't literally, explicitly fight for the preservation of slavery.
The bigger issue here is about base security and/or corruption, because...
Thirty-one extra 9mm pistols in southwestern Georgia is less than a nothingburger. That's, like, 2.37 Papaws' houses worth of firepower.
Yeah, it's more an issue of someone was able to steal Army property and they want to make an example of them. You can buy all that legally in one day with just a driver's license in GA.
My guess is that the pistols are gone at this point. One or two will turn up at auction in 15-20 years "Genuine US Army Issued!" at which point the Army will demand them back, but the chain of ownership will be too convoluted or lost to press charges.
I was thinking that, like I could probably lose half a dozen firearms from my safe and I'd never notice. How many could an army lose before someone figured out something was up? Apparently, 31.
