Iran appears to be accelerating military training for Hezbollah in preparation for a potential confrontation between the West and Iran over the latter's nuclear program. According to a STRATFOR source connected to Hezbollah, at least 250 Hezbollah fighters went to Iran from July to September for training. While in Iran, many of these operatives received training on how to fire longer-range artillery rockets like the Fajr-5 and an upgraded Zelzal-2, which is a battlefield rocket based on the Soviet FROG-7. The latter has the range to reach Israeli territory from the Northern Bekaa Valley, particularly from Hezbollah bases in the hills of Hirmil. This is a shift in Iran's training for Hezbollah — before, Iran's Islamic Revolutionary Guard Corps (IRGC) would operate Hezbollah's longer-range rocket arsenal from southern Lebanon.
