Do you know why it is a joke? Money, time, resources, bias against other MOS...there are many reasons. I have to fight to get to the range twice a year, and usually it is less then that. Did that somehow disqualify me from going to Iraq or Afghanistan, or going on patrols, getting shot or blown up by the enemy? Nope.
I'm a proponent for not making people jump through administrative hoops to exercise their 2nd amendment rights, whether they are civilians or any other uniformed servicemember. So long as their carrying of concealed personally owned weapons is consistent with existing state laws, such as a valid CHL, I would require zero additional training. If that state requires training, then swell...if it doesn't....also fine.
Whether or not someone is trained to your "standard" has nothing to do with their right to protect themselves in the event of an active shooter scenario. Everyone in this Army IS trained with firearms. Some forget that we all are soldiers first...and go through the same mandated weapons familiarization and marksmanship training when we first come in.
Now if you are talking about PVT Joe Snuffy exercising a little common sense...that is another matter entirely. PPT training (contrary to the Army view) will not prevent PVT Joe Snuffy to doing stupid stuff...nor will going to the range repeatedly prevent a ND in the hands of an idiot. We get annihilated each year with a tremendous amount of SHARP training, but do we really think that is what stops sexual harassment or sexual assault? It's a little common courtesy and common sense that normal soldiers should use for these things. This can't be taught. It is a character / personality trait.
I could be convinced to allow SOME training (particularly by JAG), if it was not employed by Commanders as a means to "unreasonably" limit or control who can carry a POW. There is a lot of gray area in what I just said. At least our lawmakers are now having a dialogue on the matter...because if it was left up to Post Commanders, none of them would ever accept this liability...and we would just continue on as we are now.
