"The first tactical exercises will take place at the Ashuluk range from August 10-16 involving the force's S-400 systems and also the gun-missile Pantsir C system in live firing," he said.

The S-400 firings will be carried out by two units from the Dmitrov district near Moscow, he said.

Four battalions of Russia's Aerospace Forces are currently equipped with S-400, and a fifth will be operational by the end of this year, a senior air force commander said earlier this week.
