According to The New York Times, intelligence provided by the US helped Ukrainian forces find and kill several top Russian generals.

At least 12 Russian generals have been killed by the Ukrainians since the invasion began.

An investigation by the British Broadcasting Corporation found that Russian troops losses in Ukraine have included elite troops and top generals that take years and millions of dollars to train.

Though the US has declined Ukrainian requests to send troops into the country, as it would be considered a direct attack on Russia, it has instead passed Ukrainian forces an increasingly rich stream of intelligence and military aid.

US officials told The Times that American intelligence was important in the deaths of several Russian generals. The US hasn't given intelligence to Ukraine about the most senior Russian leaders, officials told The Times.

The location of Russia's mobile military headquarters is one key data point that the US has shared with Ukraine.

A Pentagon spokesman told Insider that they provide detailed, timely intelligence to the Ukrainians on the battlefield to help them defend their country against Russian aggression.

The US is taking a more active role in fighting Russia's invasion than it stated at the beginning.

US officials told The Times that they were happy to share intel with Ukraine.

NBC News reported last month that the US passed intelligence on Russian missile strikes to Ukraine so it could move military assets out of the way.

NBC News reported that US intelligence helped the Ukrainians shoot down a Russian plane with hundreds of troops on board.

US intelligence agencies correctly predicted that Putin would invade Russia earlier this year, even as some European nations did not.
