Once more from the latest edition of the DEBKAfile newsletter THOSE PROXY FORCES OF IRAN AND HEZBOLLAH ENGAGED IN THE SYRIAN CIVIL DEFEATED NOTHWITHSTANDING THE WITHERING [?] RUSSIAN AERIAL OFFENSIVE IN SUPPORT?
"IRGC routed in Syria by new missile"
"The defeat that Iran and Hizballah suffered on May 6 in a battle at the Syrian village of Khan Touman showed they cannot win the war for Syria's President Assad. The clash in the village, located southwest of Aleppo, will go down in the annals of the Syrian war as the biggest defeat suffered by the Iranian Revolutionary Guard Corps and Hizballah, as well as the battle that changed the face of the war."
See at the Long Wars Internet web site a much long and better description of the aftermath of Khan Touman. Missiles perhaps some sort of modern anti-tank guided-missile to blame for Iranian/Hezbollah battlefield disaster?
This Iranian/Hezbollah formation defeated by a force of al Nusra/Al Qaeda affiliated combat units. Sunni [al Nusra] and Shia [Iranian/Hezbollah] in opposition.
Russians listened to orchestral music instead of providing close-air-support?
