The biggest problem with SF support is they are treated with kid gloves...
I was only in Group a short time, but I never witnessed or heard about anything like what you described. I'm sorry that happened and I hope that fat bastard will soon be doing the walk of shame across the street to the nearest conventional unit. Of course the fact that he's a shitbird is probably why his fat ass is in the arms room to begin with...
At any rate, I think you may have misidentified the problem. At the end of the day, every support guy in a Group reports to someone with a tab. If the support side isn't meeting the mission, then it's up to SF to fix it. The biggest problem with SF support is not that they are treated with kid gloves, but that USASFC has not made (or is not willing to make) the investment necessary to ensure that elite operators in SF are complemented by elite enablers. Why are you guys still the only comparable SOF unit without an A&S for your support troops? (rhetorical question, not directed at you Etype) Other SOF elements have managed to do it. I recognize that SF is the largest SOF formation in the inventory and it would be expensive and time-consuming to get an enabler assessment, selection, and training program off the ground, but that's what it is going to take to fix the problem that we all seem to agree exists at the Group level.
I had two SOF assignments after leaving Group. I've seen the difference between enablers who are in a unit because they got assigned there by their branch, and those enablers who had to compete to be the unit. There is no comparison; the "needs of the Army" crowd will cumulatively always be less capable than the "varsity" enabler crowd. This has nothing to do with the operators they support, it has everything to do with how those enablers got into the unit, and what they have to do to stay there. There are always some good people in the "needs" crowd, and every once in a while you'll get a turd in the "varsity" crowd. But by screening, training, and holding people accountable, the "varsity" crowd as a group will always be better.
If SF wants enabler support to improve, then SF needs to step up, recognize the problem, and commit resources to its solution. The solution I'm advocating in my thesis isn't perfect, but it's a good start and is probably better than what we have now- it is certainly better than what we had when I was with Group. With a little more research and planning, and combining it what what USASOC and USASFC are already trying to put together on the enabler side, USASFC could create an incredible training pipeline to pair the world-class operators in SF with world-class enablers.
If it seems like I'm passionate about this subject, it's because I am. 5th Group was extraordinarily good to me, and I'm still reaping the benefits of my time there. At the same time, I'm frustrated because I know that with just a little effort, the enabler side of Group- especially the intel enabler side- could be enormously improved, and that might just save some lives on the battlefield.
