I'd...just been hired by a company that sponsored leaders and authors in the ‘New Age’ and 'Human Potential Movement' (among others, we sponsored Richard Bandler and brought Neurolinguistic Programming to Washington, D.C. and other cities along the East Coast. My previous job, along with this and future jobs, follow what I believe is a possible link to MC, but that’s another story).
NLP & Bandler have been strongly linked to US mind control programs, so I hope you'll say more about that some day. It's so sad that Dream's End's 10,000 Heroes – SRI and the Manufacturing of the New Age blog posts are no longer up at WordPress. And The Wayback Machine site is down for maintenance at the moment, so I won't be able to link to his detailed history of the way that the Human Potential Movement (and the New Age in general) were mass "social engineering" projects (mass mind control, IOW). But the subject has been discussed here at RI many times. And other survivors of the programs have mentioned being used by handlers to promote covert mass mind control projects, so being employed by companies like the one you worked for might be an important part of your personal puzzle.
As for rage alters, so much disinfo has been posted online about special forces-type training of "Delta" alters that it's very, very difficult to suss out the real thing. Most of it is juicy disinfo-laced screen memories, I suspect, but some is an accurate reporting of real training programs involving DID/MPD human guinea pigs. One verifiable goal of MKULTRA was to produce couriers for the intelligence agencies and the military. Working as undercover agents in dangerous parts of the world, I assume they would need to have excellent self-defense skills. And then there's the goal of creating a "super soldier" that's also seems to be part of the mind control programs.
Since my own rage alter is a fairly well-developed personality (rather than just a "fragment"), looking back over my life I can identify a number of times that she's surfaced. That sense of being on frigid plain and the slowing of time are 2 things I learned to recognize long before I'd ever heard of MC programming. She has a particularly strong trigger around being touched by someone behind her/me and my current husband once found himself pinned underwater with her/my hand around his throat when he forgot and grabbed me by the waist from behind during a snorkeling session in the Bahamas

Then there was the winter evening when I inadvertently stepped into a disintegrating drug deal on a dark Oakland street corner. I knew it was her by the deep pleasure she felt in facing down both guys--dangerous situations evoke a thrill in her, as opposed to the stark fear they cause me. The expression on my face when she's "in front" feels very different from my usual demeanor, too. I'm small, blonde and very slight in build, so aggressive men aren't running from me due to any physical fears when she surfaces. It has to be the unholy glee with which she faces them. Scares me half to death each time it happens

And I don't recall hearing any of the wavie/gang-stalking sufferers mentioning alters at all, let alone ones with apparent hand-to-hand-combat training. If I'm incorrect about that, I hope someone will correct and clarify.
