In the Pentagon, they stated that attacks were made against American military using “directional energy”, that is, without the use of shells. Such attacks were allegedly carried out by Russia with sound waves and caused health problems. This is reported by the Politico newspaper with reference to the sources.
In the US Defense, they stressed that it is impossible to argue about any involvement in attacks, since the symptoms of these blows may appear for other reasons. Evidence of the possible involvement of Russia does not indicate the newspaper.
According to sources familiar with the investigation, the Pentagon since 2020 studies such cases, including in relation to their military. So, last fall as a result of attacks, several US military personnel appeared symptoms similar to those that happen when ORVI. However, as a result of the investigation of another similar case in Syria, it turned out that the marine had food poisoning.
