The Iranian airmen have travelled to Kazakhstan to take part in the International Army Games 2018, hosted jointly by seven countries.
The team will compete with servicemen from five other countries, namely Russia, Belarus, Kazakhstan, China and Pakistan in flying hand-launched pilotless aircraft.
The 9-strong Iranian team has taken seven drones to the games.
Iran itself is one of the hosts of this year’s Army Games.
In comments on Friday, Chief of the Russian Armed Forces’ Main Combat Training Department Lieutenant-General Ivan Buvaltsev told Rossiya-24 TV Channel that Russian Defense Ministry has sent out invitations to all NATO member states to participate in the games.
"This year, we have sent out invitations as usual to NATO member states. But only a team from Greece will take part," the general said.
The International Army Games will run until August 12 in Russia, China, Kazakhstan, Belarus, Iran, Azerbaijan and Armenia.
