Covering an area of more than 220,000 square kilometers southeast of Iran, the war games take place in three main stages.
Highlights of the first day included heliborne operation to deploy commandos, deployment of electronic warfare units, drone flights for intelligence operation, and counterterrorism operations by the Special Forces.
The Iranian armed forces hold routine military drills throughout the year.
In September, Chief of Staff of the Iranian Armed Forces Major General Mohammad Hossein Baqeri said there will be no delay or slowdown in the country’s military tests and war games, adding that Iran has devised comprehensive defensive strategies to counter all threats.
