The Russian Army uses artillery to start an avalanche for precautionary reasons. The avalanche got bigger than they expected.
Using explosions to start an avalanche under controlled conditions is a common practice all over the world, including in the United States.
However, these Russian Army Soldiers in North Ossetia got a little more than they bargained for when using their heavy artillery to trigger an avalanche.
That got a little too close for comfort. Maybe they should set up their guns a little further away next time…
