"A new insurgency is imminent, a new way to win posts and money."

Whenever the FARDC (the regular Congolese Army) can't handle a revolt or armed flareup, which is almost never, the gov. is in the habit of buying the leaders of the revolt off with a high rank or command of a military district.
So, if you are an ambitious leader with some men to command and you want to better yourself; you command your men to go forth and make trouble. They generally make trouble by murdering innocent people in the area.

Then, the gov. responds by giving the ambitious leader a high rank and a command in the army that was too weak to beat him.
