At, Within, and Beyond
Some abilities require two objects to be at, within, or beyond a certain distance from each other.An object is at a range of another object if any portion of it is inside that range as measured by the range tool. For a unit to be at a specified range, only one miniature in the unit must be at the given range. An object is always at any range of itself.An object is within a range of another object if it is entirely inside that range as measured by the range tool. For a unit to be within a range, all miniatures in the unit must be within the given range. A unit that is within a certain range is also at that range.An object is beyond a range of another object if it is entirely outside that range as measured by the range tool. For a unit to be beyond a range, all miniatures in the unit must be beyond the given range.Undeployed Units
If a unit is not on the battlefield because it has not yet deployed this game, it is undeployed. An undeployed unit is within any distance and in LOS of each friendly undeployed unit and is beyond any distance and not in LOS of each enemy unit and each unit on the battlefield.
The Clone Trooper unit is at 
of Obi-Wan Kenobi because it has at least 1 miniature whose base is at least partially inside the first segment of the range tool. The AT-RT is within of Obi- Wan Kenobi because its base is entirely inside the first segment of the range tool. The B1 Battle Droids are beyond of Obi-Wan Kenobi because all of their miniatures' bases are entirely outside the first segment of the range tool.
