On page 167, ASCE 6th Printing, the rule for smoke states:
"Light smoke rises 2 inches above the
underlying terrain and affects line of sight in the same manner as
light woods (imposing a +1 terrain modifier)."
Does this imply that smoke and woods are not cumulative modifiers? For example, if a mech is standing in light woods (+1) and is also standing on a 2" light smoke template (+1), would the modifier be +1 or +2?
