From a link the article you cite uses to say it didn't happen...
...Echoing comments in July by Gen. Mark Milley, chairman of the Joint Chiefs of Staff, McKenzie said that if he could establish that the Russians were offering payments to kill Americans, he would push to forcefully respond. But the intelligence is far from conclusive, he said.[emphasis mine]
"I found what they presented to me very concerning, very worrisome. I just couldn't see the final connection, so I sent my guys back and said, look, keep digging. So we have continued to dig and look because this involves potential threats to U.S. forces, it's open," he said, adding, "I just haven't seen anything that closes that gap yet."
A U.S. military official familiar with the intelligence added that after a review of the intelligence around each attack against Americans going back several years, none have been tied to any Russian incentive payments.
The suggestion of a Russian bounty program began, another source directly familiar with the matter said, with a raid by CIA paramilitary officers that captured Taliban documents describing Russian payments.
A Taliban detainee told the CIA such a program existed, the source said, although the term "bounty" was never used. Later, the CIA was able to document financial transfers between Russian military intelligence and the Taliban, and establish there had been travel by key Russian officers to Afghanistan and by relevant Taliban figures to Russia.
That intelligence was reviewed by CIA Director Gina Haspel and placed in Trump's daily intelligence briefing book earlier this year, officials have said. The source described the intelligence as compelling, but meriting further investigation. Nonetheless, current and former U.S. officials have said, many CIA officers and analysts came to believe a bounty program existed. They concluded that the Russians viewed it as a proportional response to the U.S. arming of Ukrainian units fighting Russian forces in Crimea, the source said....
So it seems that the report was not disproven, the evidence was reported as not being at the level where action was appropriate or warranted.
And the Pentagon did not call it a hoax, as your comment asserts.
I also find it ironic that the article cited in your comment criticizes the mainstream media repeatedly. Yet it uses mainstream media to bolster its argument.
