The June 19 defense pact signed between Russia and North Korea included a promise to provide military assistance to one another – within days Pyongyang said it was sending troops to Ukraine.
Or.. the north Koreans truck over fodder for the storm Z units from their prisons. And the Russians use barrier troops to force them to attack.
This is a horrible development that just creates more suffering.
That said maybe south Korea can send military translators for the case some get captured. It can be an epic PR tool for south Korea having a solid group of north Koreans that lived.
NK will probably threaten threaten the families of the soldiers sent with execution if the soldiers surrender. Sadly, that can make for a motivated soldier.
