“During tactical exercises with live fire, of which 60 percent of them were held at the Kapustin Yar [Testing Range] at night, problems of perfecting practical skills of the units’ command, bringing the military staff on high combat readiness, the organization of joint activity and an overall requalification of military coordination and training for the military personnel was held,” the press service said.
The Russian military unit was deployed from its base in Armenia for training.
Russia is currently looking to finalize the delivery of five S-300 missile defense systems to Iran as part of the $800-million deal signed between the countries in 2007.
The S-300 long-range surface-to-air missiles first entered service in 1978 and have since been at the core of the Soviet Union's and then Russia's anti-air and missile defense.
The system is also used by other former Soviet republics as well as some other European and Asian countries.
