General
The LOS between units is a straight line, traced from the center dot of the firing unit’s hex to the center dot of the target unit’s hex. LOS works both ways; if a friendly unit has LOS to an enemy unit, the enemy unit has LOS back to the friendly unit. If the LOS is blocked the unit cannot see, nor fire on, the target unit.
Blocking Terrain
A hex, depending on the terrain or terrain features in the hex, may block LOS. If the LOS passes through any portion of a blocking terrain hex the LOS is blocked. A unit cannot see, or attack, a unit if the LOS is blocked. A unit may see and fire into a blocking terrain hex, but not through the hex. Units in a blocking terrain hex may fire
out of the hex normally.
Hindrances
A terrain feature classified as a hindrance does not block LOS, but may modify movement and combat, and the effects are cumulative.
Hexside LOS
Hexside LOS refers to any LOS traced along the full length of a hexside between two hexes, or a series of hexsides between their adjoining hexes, and not simply across a hexside into an adjacent hex. If a hex on both sides of the hexside LOS path contains blocking terrain, even if the hexes containing blocking terrain are not adjacent, the LOS is blocked. If one hex on the hexside LOS path contains blocking terrain or a hindrance (orchard or hay stack hex), and a hex on the other side of the path contains a hindrance, the LOS is hindered, and a +1 hindrance modifier is applied to any attack dice roll crossing the hexside. If one hex along the hexside LOS path contains blocking terrain or a hindrance, and all hexes on the other side of the path are open, the LOS is neither blocked nor hindered. Once it is established that hexside LOS is hindered, each additional hindrance hex (or hexside hindrance) along the hexside LOS, on either side or through full hexes in which the LOS passes, adds +1 to the cumulative total.
