The Last Moments of A Russian Helicopter Are Illustrative

This screencap shows the last moments of a Russian Mi-8 helicopter and its crew.  Some 8 months into the war, pictures like these are all too familiar, a lone Russian helicopter flying low over the trees gets deleted by a shoulder-launched surface-to-air missile and crashes to the ground in a fireball.

So far, Russia has lost over 200 helicopters according to conservative estimates, almost all of them in the circumstance you see above, shot down by fire from the ground at low altitude.  And these seem destined to lose in even most in the coming months.
