Graham will set up heavily fortified checkpoints on the main roads heading out of Munich, so the Evacuation Choppers have somewhere nearby to drop off the civvies. The little birds will try to keep the infected off of the evacuation and transport choppers asses along with ground troops on APC's, all armed with assault rifles, light machine guns, and shotguns. The APC's are allowed to pick up survivors on the street that aren't bitten. If they're bitten they're shot without question. The APC itself has a 50. caliber machine gun on front top area and a 308. machine gun on top back area. Ground troops will also try to scour through the various homes and apartments searching for survivors. When Munich has been evacuated the little birds will have free reign to take out the remaining infected.
The choppers patrolling the city:
Little Bird gunships: A small helicopter with a mini-gun and missile launcher
Transport Choppers: Choppers with an on-board mini-gun and has seating for a dozen people
Evacuation Choppers: Choppers without any weapons, it has enough room for 30 people.
