From that latest edition of the DEBKAfile newsletter.
Add to the total package of Russian military involvement in the Syrian Civil War some electronic warfare [EW] systems of some impressive capability.
Devoted readers to the blog already familiar with these systems.
"Russia overrides Middle East cyber waves"
"Moscow has augmented its military presence in Syria and Iraq with two state-of-the-art weapons: the Ilyushin-20 (IL-20 Coot) surveillance planes in both countries and, nine Borisoglebsk 2 electronic warfare systems atop a Syrian peak. Both are among the most sophisticated of their kind anywhere. Last week, after Baghdad gave Moscow permission to use its Al Taqaddum air base, the Russian spy plane first sighted in Syria was spotted in Iraq. The electronic warfare system is capable of neutralizing air and ground military operations of US-led operations forces in Syria and Iraq by jamming almost any radio signal"
These systems very complex and without question [?] having to be manned by Russian personnel.
