This is something that several people have claimed to be a target of. They have become known as "targeted individuals."

A subcommittee for Homeland Security was recently held to discuss this technology and the targeting of US government employees and their families. This is commonly known as, the "Havana Syndrome," and dates back to 2016 when US diplomatic personnel in Cuba experienced unexplained health problems.

"Guys, if your, assessments here are correct, these are very covert weapons, aren't they? They don't leave behind bomb fragments, bullet holes, etc. They could absolutely be used by our adversaries and have very low levels of, very easy to deny if they were even there, that they were used. Is that correct?" ~ Eli Crane

"That's correct. There's no entry or exit wound. How they're designed is to make the target feel like they're crazy, like they're imagining things, especially on the low duration. the low intensity, long duration hits." ~ Greg Edgreen

"Have any of you three panelists ever seen one of these weapons?" ~ Eli Crane

"I have seen a 1991 version of the weapon. And it looks like a satellite dish with a unit this size attached to it. And, of course, over the years, miniaturization has been possible. Obviously there is a limitation to how miniaturized it can be because of the antenna size, which is always related to the wave. But still, it is something that can be well contained in the trunk of a car or even a large backpack. My experience shows that it can be cobbled together. It's something that can… A rough crude version of this that would probably require longer exposure than the more advanced version, that has been tested, as we see from this document, can be put together inexpensively. But again, I would abstain from commenting further, lest I encourage people to try it at home." ~ Christo Grozev
