S-300.

Russian response to the downing of the Il-20 reconnaissance warplane retaliation as previously hinted at least to this extent indirect. Thanks to the Investment Watch blog for the heads-up.

"Russia Retaliates to Downed Airplane: Israel Will No Longer Be Capable of Bombing Syria With Impunity"

The Russian two-step in action to consist of:

1. Provide Syrian air defense with an upgraded and more capable S-300 surface-to-air missile system.

2. Jamming of all weapons systems [electronic guidance] used by aggressor warplanes [Israeli] firing at targets located within Syrian territory.

See the Maxim Suchkov tweet regarding item # 2.

    #Shoigu: "#Russia will jam satellite navigation [GPS], on-board radars and communication systems of combat aircraft that attack targets on #Syria/n territory, in the regions over the waters of the #Mediterranean Sea bordering #Syria"

The Syrian will be ready and able in an instance to deploy and use in an effective manner the S-300? Russians will be embedded with the Syrian operators? A push-the-button-now sort of familiarity will be needed?
