Russia and the Norks

 Business Insider:

Russia is relying so heavily on North Korea that it's getting 50% of its ammo from Pyongyang, Ukraine's spy chief says

...

Speaking at a press conference in Kyiv, Budanov said Pyongyang was also providing Russia with 155mm self-propelled howitzers and multiple-launch rocket systems. He has previously said that these were the M1989 "Koksan" howitzer and the M1991 system.

Over the last year, North Korea has increasingly dedicated resources to help Russia sustain its war against Ukraine. It deployed an estimated 11,000 to 12,000 troops in Kursk late last year.

Pyongyang's involvement comes as Moscow and Kyiv focus on outlasting each other along the largely stagnant front lines and as Russia digs deep into its economy to maintain recruitment and weapons production.

North Korea isn't giving its resources away for free. Its leader, Kim Jong Un, is reported by South Korean intelligence to be receiving technological assistance from Russian experts, as well as food and cash from Moscow.

This is more evidence of the weakness of the Russian economy and its military.  When you consider that Ukraine is also not a first-rate power, it tells us something about Russia's potential when it comes to conventional arms.
