"We need to hurry, Phoenix. The rebels have already begun their operation."
Ulrich Olsen

Cuckoo's Nest is the tenth campaign mission in Ace Combat: Assault Horizon Legacy.


Enemy guerilla activity has been going on for a while in the Chopinburg Rainforest. The Allied ground forces have been fighting the guerillas by cutting off their supplies, but the Rebel Forces are now trying to deliver supplies from the air. We fear they may be trying to deliver chemical weapons as well as ammunition to the guerilla forces. Prevent this at all costs. Phoenix, you are to fly to the drop zone and destroy all cargo dropped by the transporters before they reach the ground. Not even one of those crates can fall into the guerilla's hands [1]


The mission's primary targets are several C-17 transport planes that continuously drop cargo crates behind them, which are also primary targets. The crates must not touch the ground, and can only by destroyed by the plane's gun. The C-17s appear one at a time, and appear once the previous one has been destroyed.

All dropped cargo as well as Rebel transporters have been destroyed. Thanks to today's victory, the army can hold an even longer sweep operation. Now it's just a matter of time before the guerilla forces fall. Even without the ability to lock on to your targets, you did well. But I just got a message from HQ about a new mission. Get ready, Phoenix.[1]
