I talk **** about the wing but damn it, those Russians are flying close air just like Marine Corps Cobra pilots. They aren't scared to get in the **** and neither are those Russians
Impressive stuff but surely they're just asking for trouble - any man and his dog with an RPG must surely be tempted to take a pot shot against what would be an incredibly valuable target? The Russians would find it hard to swallow the loss of a Hind from a propaganda perspective, particularly if a rebel group managed to film its loss.
Also, there seems to be lots of stuff flying around in the footage. Hard to make out what it is - birds, debris? Editted to add: Also at around 32 sec there are ground impacts as the two Hinds fly away - poss collateral impacts from AA/small arms etc aimed at Russian helos?
