Armies march on their stomachs...
Insurgents fill their stomachs with food taken as needed from other parties in the area. That taking process usually involves arms, and at least the perception of the people with the food of the willingness of the insurgents to use their ammo.
Of course governments take food at gunpoint all the time as well. Ask any Venezuelan or North Korean farmer.
