Red: approx firing arc
White: better

Idk if this has changed or if it has always been like this in coh2, but squads in the blue areas can be hit from mg without changing windows. Pretty fubar because those areas are outside of the corner of the building, so the MG can cover 1 whole side and a partial space of the opposing sides from one window. It seems like the coverage is 90 degrees, but the arc should originate on the corners not from different sides of the building.
