Without sending troops, the U.S. wages 'hybrid warfare' against Russia

Sounds like a hybrid answer on both sides.

PO1 William "Chip" Nagel
..."Here's a look at what it means in the current conflict:

Q. How did "hybrid warfare" enter the military vocabulary?

The first prominent figure to talk about it publicly was James Mattis, the retired Marine Corps general and former U.S. defense secretary. He used the term in a 2005 speech, though he didn't go into detail.

Then in 2013, the Russian military's chief of the general staff, Gen. Valery Gerasimov, gave a speech on hybrid warfare that caught the attention of some Western journalists.

Gerasimov, it turns out, was not talking about a new Russian military doctrine. He was actually addressing what he believed the U.S. was doing to support uprisings around the world. Gerasimov speculated on how Russia might respond but wasn't proposing a new Russian approach.

But in 2014, Russia stealthily seized Ukraine's Crimean Peninsula using disinformation, cyberattacks and "little green men" in unmarked military uniforms. There was virtually no fighting. Some in the West described this as an example of the "Gerasimov doctrine," though there has never been evidence that such a game plan exists.

Mark Galeotti, a British journalist who closely follows the Russian military, wrote a mea culpa in 2018 titled "I'm Sorry for Creating the 'Gerasimov Doctrine.' "

"To my immense chagrin," he wrote, "I coined the term 'Gerasimov doctrine,' though even then I noted in the text that this term was nothing more than 'a placeholder,' and 'it certainly isn't a doctrine.'"...
