The Usean Rebel Forces were engaged in guerilla warfare with the Usean Allied Forces in the Chopinburg Rainforest. The Allied Forces attempted to fight the rebels by cutting off their supplies, but the rebels attempted to deliver supplies through airdrops instead.
At 1500 hrs, Phoenix entered the airspace over the Chopinburg Rainforest. In addition to destroying the transports and the supply containers that they were dropping, Phoenix also destroyed their escorts and attacked the rebel ground forces. Soon, all transports and their cargo were destroyed. 
The rebel supply operation failed, as the supplies were intercepted by Phoenix; as a result, the guerrillas operating in the Chopinburg Rainforest would soon fall to the Allied Forces in a sweep operation.
