This is coolbert:

From MARCO POLO through Harry:

Russian submarine firing cruise missiles targets ISIL targets:

"the Russian Navy [reported] that one of their diesel electric submarines fired cruise missiles from eastern Mediterranean at a target in Raqqah (Syria), which was the first operational firing of cruise missiles by a Russian submarine."

"The submarine was the 'Rostov na Dnu' [Rostov on the Don] of Project 636 . . . (NATO's 'improved Kilo').  The Russians said that the effect of the attack was now being investigated by air and satellite reconnaissance."

Kilo able to fire the Kalibr or Klub cruise missile.

 Everything but the kitchen sink being thrown at the Islamic State. Maybe even eventually the kitchen sink too?
