Kaesong has quite a bit in common with Casere - both are heavily populated industrial worlds where the environment has suffered because of pollution. But unlike Casere, Kaesong has little in the way of military value - its factories are geared towards private consumption. It's not the needs to the Dragon that has ruined the planet, nor the necessities of war, but the kind of greed you normally associate with Lyran merchants.

Kaesong's factories produce a good portion of tradable consumer goods for the district and beyond. It is helped by its shallow gravity well and well-known pirate points. The system is always alive with dropship traffic, and the Combine has largely given up policing it. After all, if an enemy wants to sneak in, what is he to do? Kill civilians? Blow up some worthless factories?

Nevertheless the Dragon maintains a military presence here. The current DCMS mech garrison has been scaled down, but there is said to be at least a battalion's worth, maybe more, of mercs on the planet. These merc are from at least two different companies - and may not be deployed in the same locales.
