This is what happens if you send Buk rocket systems to terrorists.... Happy now, Russia?[/QUOTE]
Well, looking at this...
[quote="Nickodemos, post: 121434436"]Just so everybody's clear, operating advanced SAM systems such as the Buk is beyond the ability of the average insurgent cockmongler. If there are such systems employed on the separatist side, they're crewed by personnel from the Russian air-space defence brigades and get their orders from the Russian chain of command.[/QUOTE]
It would be hard for anti air missile to originate from Russia, they have around 25 km of operating range (BUK). Other thing would be either trained separatists /Ukraine army trigger happy crew of mobile launcher unit.
