Iran's air defense units test performance air defense artillery systems during military drill 210212.

The drills were staged by the air defense units of the Iranian Army and the Islamic Revolution Guards Corps (IRGC) on the second day of the 'Sarallah' wargames underway in Iran's Southern regions.

In the current phase of the drills, hypothetical enemy aircraft and Unmanned Aerial Vehicles (UAVs) intruded into the airspace of the wargames' general zone in low altitude but were detected, identified and confronted by Iran's integrated air defense network's electronic systems.

The performance of 35mm Oerlikon (Samavat) air defense artillery systems, Skyguard and Rapier air defense systems which are now equipped with electro optic and laser telemeters was assessed in the drills.

Iran has recently renewed and upgraded the weapons and defense systems of its air defense units. Late in September, Iran equipped its air defense units across the country with large numbers of the home-made Mersad Air Defense Missile System.

In November and during the massive air defense exercises in Iran, the power, capability, weapons and military systems of the Rapid Reaction units of Iran's Air Defense Force were tested.

The Iranian Air Defense Force's rapid reaction units used their state-of-the-art, home-made weapons and systems, including multi-frequency radar equipment, anti-aircraft canons and different types of air defense missiles to force hypothetical enemy aircraft out of the country's air space.

Later in the drills, the rapid reaction units tested their ability against the hypothetical enemies' surprised night raids and blitzkrieg with full radio silence.
