To some extent, however this war has already done a massive amount of economic damage to future Russian arms sales as it has showcased how much Russia has been unable to evolve effectively in their weapons development, a similar situation is also going to occur if other allies of Russia start seeing footage proliferate all over the international community of their supposedly cutting edge multi-million dollar weapon systems getting annihilated in spectacular fashion.

It isn't just that Russian military equipment clearly doesn't work that well in a lot of cases, it is that Russian military doctrine clearly disdains the lives of its soldiers in a way that I don't think most foreign technologically advanced militaries can even pretend to respect past a certain point especially with how advanced warfare and technology has gotten in general.

This has a real political/military impact, I am not saying countries aren't willing to pay it that are allied to Russia, I am saying Russia must in some way be paying a serious cost to make up for the damage to future arms sales and perception of military might it will do to their allies who are sending their troops and equipment to the same meatgrinder Russia is sending its own soldiers.

Not to mention those countries risk their equipment falling into Ukrainian hands and then having any disguised technological advantage to them discovered by the enemy long before that country even has the chance to use their weapon systems in a domestic war that is actually existential to them.

The Koksan could be a very effective and attractive weapon systems for a lot of allies/associates of Russia and North Korea to purchase, but because Russia cannot protect its artillery they keep getting blown up which doesn't look great for the weapons system even if it was properly modernized with digital fire control systems and such.

If Ukraine gets their hands on some Koksans I am sure they could produce a far more modernized, better version of it given enough time, which is a big problem for the political and military power of North Korea. Do you see how this inherently introduces tension between North Korea and Russian military relationships?

Not that the US military didn't already get its hands on it an older Koksan least for awhile.

A Koksan artillery piece was towed to University of Anbar around the 29 May 2003. At this time, soldiers from the United States 2/5 Field Artillery Battalion had been occupying the grounds of the university. The self-propelled weapon was towed to the university grounds so that it could be returned with the unit as a trophy, an idea that was eventually abandoned. At this time soldiers from the 2/5 Battalion disabled the gun with a thermite device. Eventually, the 2/5 Battalion was reassigned to a new area of operations and the cannon was left at the university.[citation needed]

This is a dead end for Russia/Putin. The amount of artillery given by North Korea with the Koksan 170mm and the MLRS systems is major, but I am doubtful Russia can even politically afford to commit them decisively to battle when it matters or else Russia risks a Strategic failure with footage of a major amount of North Korean artillery systems annihilated in huge explosions being shown all over the world to the shame and rage of North Korean military leaders whoever they may be in this context.

I am assuming Russia will heavily use Koksan like artillery systems in the future, but I think they likely won't be fielded at the most intense parts of the Ukraine war... where they desperately need to be.. until Russia can mostly do so with its own troops using mostly "Russian" Koksan equipment. Maybe I am wrong, but that puts this reintroduction of a decisive artillery system in Russia's favor out of the aperture of the near future and I think that will come too late to matter given how badly Russia is bleeding resources and human lives right now.

You have to remember the North Korean military is a professional military, they haven't ground through the vast majority of their military veterans like Russia has this late into the war, North Korean military personnel are coming into a situation where essentially they are fighting for an army of scared, angry children who know nothing about war and were just handed a gun and told to attack led by a shrinking number of command staff that have any clue what they are doing.
