# Choosing a Phase
## Phase Layout
Phases are grouped by Territory Battle.
Each phase is a button that will drop you into the Phase Picker dialog with a default layout.
## Phase Picker
Example of sandbagging top and bottom for phase 4.
The Phase Picker will display a full graphic layout of the entire TB's phases.
Using the buttons, select the specific phase layout that your guild is attempting for the current phase. Often this requires mixing zones from multiple phases in a strategy referred to as "sandbagging."
Once your layout is complete, click the green button at the bottom to navigate to the Platoon Assignment tool with your chosen phase layout.
