North Korea has a massive army. That is where almost all of their food, fuel, and money goes to.
And the Chinese army reinforcements sent to Manchuria are only bank guards because they keep starving North Korean soldiers from crossing the Yalu, with weapons they've taken off base, to rob Manchurian banks so they can buy food.
What you call an army is three foodless days away from mutiny.
Please update us as to numbers and effectiveness.
Please be specific with cites as numbers pulled from one's arse are of no help.
Thanks,
NK Army
