After the cutscene, head to the transmitter marked in the map. Hack the transmitter control and destroy it. Next, Alessia will tell you to help the rebels and prevent too much losses on your end. There will be a gauge that will display how close your forces are from defeat or winning the war. Head to the locations that will be marked in your map and defeat the enemies there as fast as you can.

The first battle will require you to destroy the armored personnel carriers that will land via amphibious ships. After that, you have to help the rebels overrun by military tanks. Hijack one of the tanks and use it to destroy the others. Once done, leave the tank you commandeered and destroy it as well. Finally, head to the next location and destroy the enemy choppers pounding a rebel position. Hijack one of the choppers and use it against the other targets. After clearing the battlefields assigned to you, destroy more military vehicles and personnel until you fully tip the gauge to your victory.

Church chopper battle

The mission objective will be updated and you have to board the marked chopper. Jump from the chopper and fly straight ahead; don’t alter your direction and wait until your grappling hook marker becomes available. If successful, Rico will do the rest in the cutscene. Mission complete.
