Line Of Sight (LoS) defines the technical requirement for a Unit to Nominate a Target during Ranged Combat or when resolving Support Card effects. To verify visibility, the player must establish a straight Trace from any point along the attacking Unit's designated front Base edge to any part of the Target Unit's physical Base footprint. The Unit Base is the absolute mechanical authority for this calculation; physical attributes of the miniatures, such as limbs, weapon barrels, or antennas, are entirely ignored. Visibility is confirmed if at least one Trace can be drawn between these points without intersecting a prohibited obstruction.
A Trace is categorized as blocked if it passes through the footprint of LoS blocking terrain or the physical Base of any other Unit. Bases belonging to the same Unit are considered transparent to one another and never obstruct a LoS Trace.
- Units occupying Elevated Terrain ignore Line Of Sight obstructions caused by intervening Units or Terrain features located at a lower elevation.
- Specific Unit Keywords establish exceptions to standard visibility logic. The Towering Keyword dictates that Line Of Sight to or from the Unit cannot be blocked by standard obstructions. The Indirect Keyword authorizes the Unit to Nominate Targets even if a valid Line Of Sight cannot be established.
