Would not be surprised. In DRC we traded (with low effect) discipline and no civilian harassement against food for the FARDC who were not payed by the government.
As some say: peace has a price, just find it.

But it's an old concept. The may-may in DRC went up to the point to take hostages to get aid. Even government official who were on their side.
The result in the end is quite conter productive as Gov makes sure those places are margenalised after.
