How do you extend March distance I need to defeat zombie lair?

Once I click on the map, how do I locate my alliance?

In the world view, tap on the map / binoculars icon near the bottom left. You will see a state overview. You should then see blue tags for your alliance members locations and a red one for the leader. These will usually be in a group. Tap there to go find them. The tags can get hidden under super weapon icons, or they maybe be turned off. Use the selectors on the lower right to turn on and off parts of the map display.
