Going AWOL | Walkthrough Homefront: The Revolution Guide
After talking to Ned, go to the first floor and take the pipe bombs from the table. They will be useful during combat with armored vehicles. After taking the bombs, you will receive a task to find a missing patrol, which location will be shown on your map. It's a bit of a trek, so you might as well take over strategic outposts on your way (more about strategic outposts in the red zone is in the chapter Red Zones)
Regardless of undertaken strategy, you have to get inside the hangar shown on the screenshot. Inside the hangar you will find few armed soldiers and an armored vehicle, which should be avoided at all costs. One burst from such car will kill your character. Choose a well-protected spot (a wall, for example) and attack your enemies, aiming for their weak point - head.
After you killed all enemies, enter the hangar, and hide behind one of the containers to avoid direct contact with the armored car. The closer you are, the greater the possibility that it will take one pipe bomb to destroy said car. After the fight, go upstairs and talk with the resistance member to end the mission. You will receive another 500$ for the mission.
