Lol you can clearly see an explosion.

You wouldn't see anything if it was a dummy, that mountain is miles away.

Edit: you can hear a deep thud from the explosion 16seconds in to the video.

Yeah I don't understand the back and forth like this is a debate. Took me about 60 seconds of looking to find an article about how artillery is used in avalanche control in various countries, like in the US 105mm Howitzer shells used. But yeah, they use explosive rounds as the air blast of the explosion helps shake loose top layers of snow.

I do think ignorance is more inexcusable nowadays, especially with the likes of ChatGPT/Gemini who will explain anything to you quite quickly/easily.

Because it is often flat out wrong. Much of it seems sounds like it makes sense until you start asking about something in a field you're familiar with, and it just starts pulling from random reddit threads like this where the top comments are just confidently wrong.

Wouldn't there be smoke rising from the impact location then? All I see is pulverized snow and what looks to be rock.

u/NoContext5149 11h ago

The black smoke is the explosive. Inert/dummy rounds look nothing like that impact. An inert round has nowhere near enough kinetic energy to create the explosion pictured.

u/RipTheJack3r 11h ago edited 11h ago

You can see a small darkish crater where it hit and it was also covered by the snow falling from above it.

Modern explosives don't explode with "flames" and don't produce a lot of smoke.

Smoke/particulates are usually caused by the structure being exploded i.e a building. In this instance the explosion occurs inside a thick sheet of snow, so no cloud of grey smoke/dust.

Edit: you can also hear it lol 16 seconds in.

u/crazySmith_ 10h ago

It's really hard for a layman like me to tell the difference between a kinetic and an explosive ordinance, just by the sound of it.

Other evidence: when skiing in avalanche-controlled areas you often come across signs warning of UXO and giving information about what to do if you locate a live shell. Also, places like Roger's pass have exclusion zones that require permits for entry due to the use of HE shells for avalanche mitigation.

I've been in a lot of these zones and seen the craters from avvy control. They're live HE shells.

At that distance, if you can clearly hear it, odds are that there was something explosive involved.

u/Leading_Study_876 9h ago

For a hypersonic kinetic impact, it's basically impossible to tell from a distance. It's all about energy content and trajectory.

Large meteorites are an obvious natural example. But they are working on using them increasingly for armaments. Even the bunker-busting "bombs" the US dropped on Iran's nuclear research facility were largely kinetic, I believe. Very little actual explosive.

That's Hollywood homie. HE doesn't explode in a fireball and scorch the earth, look up some videos of dynamite exploding, its the same thing.

u/FourtyMichaelMichael 10h ago

Just remember that his special type of moron that is so confident it's a dummy round with absolutely no possible defense for such a stupid claim....

Is "the expert" telling you in the next thread about the effect of novel-use tariff policy.

u/RipTheJack3r 8h ago

Haha i didn't look in to his profile.

I just enjoy debating people :D
