After placing the terrain, it is time to choose which side of the table each player deploys on. Normally, this is the longer sides of the table. Each player rolls a dice and whoever rolls highest picks the side of the table they wish their army to start on and deploys their first unit. The two players then take it in turns to place their units until they are finished.
All units (not including characters) costing less than 50 points must be placed at the same time. All characters must be placed at the same time after all your other units have been deployed, but may be set up in separate locations or units in their deployment zone.
When deploying your units, place them at least 1" apart so it is made clear which units are separate from each other.
