E.6 AERIAL LOS HINDRANCES: Level 2 SMOKE is considered a Hindrance to Aerial attacks/Sighting TC only if the SMOKE is in the ground target/firer's hex. Level 4 SMOKE (i.e., WP and Blazes not Dispersed by a Mild Breeze—regardless of the elevation at which it originates) is considered such a Hindrance if in the ground target's/firer's hex or adjacent to it in front of and along the LOS to the Aerial target/firer. SMOKE in the Aerial unit's hex is not a Hindrance; only SMOKE in or adjacent to the ground unit's hex is a factor in LOS to/from Aerial units.
