According to Western diplomats, a Russian expeditionary force has already arrived in Syria and set up camp in an Assad-controlled airbase. The base is said to be in area surrounding Damascus, and will serve, for all intents and purposes, as a Russian forward operating base.

In the coming weeks thousands of Russian military personnel are set to touch down in Syria, including advisors, instructors, logistics personnel, technical personnel, members of the aerial protection division, and the pilots who will operate the aircraft.
