As a company commander (not in Regiment), I loved summarized Articles 15. Discipline is maintained, examples are made, and with a little "14 and 14," I get the rocks around the company area repainted (or whatever). Heck, you can give give the Art15 and suspend the punishment. But now with the Art15 in place there's a paper trail if the Soldier screws up again. Best of all, if there are no further issues, the summarized Art15 goes into the shredder when the Soldier leaves the unit, like it never even happened. IMO the summarized Article 15 is an underutilized tool in a commander's tool box.
Bringing my above statement back to this thread, there is a tendency in the SOF community, in which I've spent considerable time to kind of ignore any but the most grievous offenses (and sometimes even those). For one thing there is the tight-knit nature of the organizations. Then there's the "hassle" of paperwork, or looking at counselings or UCMJ as "weak leadership." But there's also the issue, often unspoken, that many of the people in these units have dirt on each other, and anyone trying to uphold the standards will get their own misconduct brought to light, or they will be ostracized as a "rat" by their brethren.
Or, if you're an SF NCO in Africa, you end up getting murdered by SEALs.
Some units hold to standards better than others. Although I was never in the Ranger Regiment, I worked with them closely on most of my tours downrange. They are the unit I most liked supporting, because they are disciplined, thorough, and standards-driven. I wrote about this a little bit in the book "Violence of Action."
At any rate, what SOF appears to need right now is not a change in "ethics," it's a change in "ethic," as in culture. That is extraordinarily hard to change. GEN McChrystal did it for JSOC (see also "Team of Team") but sometimes you have to take an organization apart and reconstruct it to rip out the bad culture and build up a new, better one.
It might be that time for certain SOF units.
