It said the drill marks the first time a NATO ally has taken part in the training, amid growing tensions between Moscow and NATO members.
"We're using lessons learned from Ukraine," a US Army Green Beret officer told the AP last week.
"All of those effects that we're seeing either Russia or Ukraine having to overcome—we're doing our best to replicate," he said.
The exercise focuses on the latest techniques in drone warfare, many of which Ukraine has developed during its war against Russia.
It also highlights how the United States, its NATO allies and Ukraine are working together to counter the threat of potential Russian aggression against a NATO country, even as the Trump administration has warned of possible troop reductions in Europe, according to the AP.
CIA chief John Ratcliffe visited Moscow last week to warn Russia against attacking NATO members, according to The Wall Street Journal.
Western officials and US analysts say Moscow seeks to carry out sabotage and cyberattacks against NATO countries, but Russian President Vladimir Putin wants to avoid direct confrontation with the alliance.
A senior enlisted soldier familiar with the exercise told the AP the training scenario is expected to be conducted several times a year.
He said he expected most, if not all, of NATO's 32 members to express interest in sending troops to take part, the report said.
