An Insurgency

An insurgency could bring down the North Korean regime! North Korea has never displayed its ability to fight guerillas or insurgents. Maybe they don't need to learn, they know guerilla tactics themsleves. Let's look at Afghanistan. During the Soviet occupation, Mujahedin terrorized Soviet and Afghan forces. Using guerilla tactics, combined with support from the US and Pakistan, they succeded. Now Afghanistan is very mountainous, and so is North Korea. Light artillery pieces would be used like at Siachen glacier, the world's highest battlefield. Hleicopters need clear landing zones. Mountains don't have that kind of clear space. North Korean air support would be somewhat ineffective, seeing how most of their aircraft uses outdated equipment and carry light payloads. Armor would be ineffective too. They would be sitting ducks for handheld anti-tank missiles like RPGs or LAWs. The key element to stopping them from taking over positions is MANPADS. Man Portable Air Defense System. They were used by Mujahedin in the 80s and brought down Soviet helicopters and made Soviet bombing ineffective. They key here is the MANPADS and light weapons.
