Description: Covering Terrain contributes to Cover when drawing Line of Sight through it. The bracket (X) indicates if the terrain contributes to Soft Cover or Hard Cover.
Certain Terrain Features (such as Ruins and Fields) only count as Covering Terrain for units in contact with them. Ignore any Terrain Feature the shooter itself is located in for Cover purposes.
Covering Terrain always has a bracket (Height Y) associated with it that corresponds to the largest Height where this Terrain Feature can contribute to Cover. For example, Fields are Covering Terrain (Height 3), this means that anything with a Height of 4 or above cannot claim Soft Cover from Line of Sight drawn through a Field they are in contact with.
