Okay, if you insist. But what about drunk? Lots drunken soldiers thereabouts. Again, could have been deliberate, with or without orders from higher up. I’m just not ready to call it either way.
That old Soviet junk is pretty unreliable, anyway. I remember back in the late 1990s, seeing for myself the sorry state of the Russian army (it was painfully pathetic at the time), all I could think was “And we used to be so scared of the Red Army?” Regarding their rockets and missiles, a Russian officer wryly remarked, “Mostly, they do not work.”
As a matter of fact, you can drive away in most of the Soviet tanks sitting on static display since 1945.
In order to fly a Mi-24 helicopter sitting a couple years without maintenance you only need to pour water into batteries.
