In Israel, in areas bombed by Katyusha rockets, the most damage to humans comes from the ball bearings packed into the heads of the bombs, creating a splatter of shrapnel in every direction and killing anything left outside and unprotected.
The dairy farmers do their job in flak jackets and helmets.
Not in flak jackets and not in helmets, though, are the cows themselves. No dead cows appear in this shot, but six cows previously in this metal frame did. You can see the many little holes in the metal where the ball bearings went right through.
The usual process is that sirens go off to announce incoming rockets, at which point anyone still in the area goes to bomb shelters. The dairy farmers, lacking a proper shelter, have improvised this series of concrete barriers which they crawl into and thus avoid the same fate as the frame and the trapped cows.
