Iran's Supreme Leader Ayatollah Seyyed Ali Khamenei praised the Iranian Army for its significant achievements in areas of military training, discipline and production of equipment, the semi-official Fars news agency reported on Thursday. Army's progress in these fields has largely boosted the country 's power, said Khamenei on Wednesday at a cadets graduation ceremony at Martyr Sattari Air Force Academy. 'The armed forces... have achieved remarkable progress in the production of military equipments by relying on their faith,' Khamenei was quoted as saying. He described the country's air force as the pioneer of home- made military equipment production. Iran has made significant progress in designing and creating warfare systems in recent years. On Wednesday, Iran said it would test-fire its domestically built advanced mobile missile system of S-300, similar to that of Russia.
