Nine Ukrainian battalions are currently interoperable with forces of NATO countries, Chief of the General Staff of the Ukrainian Armed Forces Viktor Muzhenko said.

"The battalions are continuing to undergo training with the help of foreign instructors, which started back in 2015. There are instructors and servicemen from the U.S., Canada, the United Kingdom, Lithuania, Latvia, Estonia, and Poland in Ukraine today… And we have currently achieved the necessary interoperability of at least those nine battalions that have already undergone training," Muzhenko said in an exclusive interview with Interfax-Ukraine.

The joint training of troops concerns units of the mechanized, airmobile, and special forces, he said.

"In addition, NATO standards are used as a basis and get adapted to our conditions, considering our experience of combat actions. By the way, servicemen from NATO countries have been making amendments and adjustments to their standards proceeding from our experience. That is, we are not just blindly copying something but are creatively approaching the relevant standards, taking into account the combat experience we have gained," he said.
