I can't imagine Russian officers or generals saying such things to the media. They talk in a way to show they just do their job, no foot-stomping, chest-thumping and "kill em all" shouts.
Such words make "coalition" commanders look like murderers to me. Just my HO. I will never understand such things. They have orders and directions, they simply have to do what they are supposed to, without all that rhethorics about "hammer time" or "nemesis". Such words should be said by stinky politicians.
Damn, they don't even fight for their land and security of their people... Good addition to the agressor's image.
