"This is the kind of crap the Koreans send. Only 1 shell out of 5 fires" - Russian soldiers show how they wash grease and rust off 82 mm mortar shells.
North Korea’s army which, whilst having a stranglehold on available resources in its threadbare economy, hasn’t seen combat since the 1950s. Its actual combat readiness may fall short of its rhetoric.
South Korea is going to have a wealth of embarrassing NK military footage from this to use in their cross border propaganda deliveries. That could damage morale inside North Korea in a way that’s never been seen before.
Fingers crossed this dumb decision hurts their regime hard.
To my knowledge, people close to the borders where propaganda can effectively reach are already quite aware that their government is a joke. They're just stuck there.
