Unit Boundary

(Rule)
Description: A Unit Boundary is an imaginary rectangle around the outer edges of the unit. The Unit Boundary of units composed of models on round bases is identical to the area occupied by their bases (this means that their Unit Boundaries are not a rectangle but a circle).​
A unit usually cannot be inside another Unit Boundary, unless the units are overlapping (see figure figure/arcs and ).

For the purpose of drawing Line of Sight to a Unit Boundary and determining if its unit benefits from Cover, the Height of the Unit Boundary corresponds to its unit's Height (see ; Model Rules such as Skirmisher, Tall, or Towering Presence can affect this).
