Desperate Russian becomes victim of physics

This video shows a Russian soldier in an undisclosed location, playing the last card he has against an overhead Ukrainian drone. Unfortunately, throwing a grenade straight up has certain ramifications, and therefore viewer discretion is advised. I can understand the desperation at play here. After all, the soldier has to assume he's probably dead either way. But perhaps by virtue of the weight of the grenade, or the effects of gravity, or the shortness of the fuse, he makes some pretty severe miscalculations- let's not forget that even succeeding would have meant shrapnel and most of a drone getting blasted down into his face. What goes up, as they say...
