This was reported by UNIAN.
"To date, more than 18,100 Ukrainian Armed Forces personnel and nearly 4,000 military instructors have been trained by the our mission," the British Embassy in Ukraine said on Facebook on August 17. "Op ORBITAL has deployed over 2,500 British military personnel and 400 courses."
The Embassy says the process has been mutually beneficial with the UK's military learning from the experience of our Ukrainian counterparts.
Operation ORBITAL in brief
In 2015, the UK established a training mission, Operation ORBITAL, in response to a request from the Government of Ukraine.
In 2018, the UK expanded the scope of Operation Orbital to deliver training to the Ukrainian Navy and Marines, who face increasing threats in the Black Sea and Sea of Azov.
In 2019, the UK extended the mission, for another three years, until March 2023.
All trainings are of a defensive nature and take place away from the conflict zone in eastern Ukraine, it said.
