I'm probably over thinking the following, so others input and interpretation would be much appreciated.
Several schemes (Breakthrough for example) and a few triggers (No Witnesses) state that the may be revealed/triggered ' if there are no enemy models within X" and LoS of this model...'
My question is, does the distance and LoS have to be applicable to each enemy model? ie if there is an enemy model further away than X" but has LoS, they don't count and the scheme can be revealed or trigger used.
