2 units atop, even surface, 20 m. Your opinion: LOS blocked. Strange¡¡
Yes, in this game. center dot to center dot and LOS goes through the Oil Refinery. Is that infantry unit at the bottom of the refinery or the top. The only way to the top is with the ladder and only during assault phase. Other than that you can get down anyway. The surrounding hexes block LOS to the centermost hex.
