AD = Air Defense.
Here begins a series of blog entries the topic of which is the Syria Civil War and how it has become to a much greater degree a war of foreign interventionists and proxies versus other foreign interventionist and proxies. At various levels.
Thanks in all instances to the latest edition of the DEBKAfile news letter
"Russian troops were involved in Iranian-Syrian clash with Israel"
"The Syrian anti-air missiles which hit an Israeli F-16 early Saturday, Feb. 10, are part of a system operated with and commanded by the Russians from their Kheimim air base. The F-16 was shot down during an Israeli air strike against the Iranian mobile drone command vehicle at the T-4 air base near Palmyra, which launched a UAV into Israeli airspace that morning . . . The second much broader wave of Israeli air strikes against Syrian and Iranian targets later Saturday morning was also attacked by air defense missiles which were fired from Lebanon as well."
