Your arc of vision is a 60° wedge to the front. On a map, your only “front” hex is the one directly ahead of you. The hexes to either side of this are “side” hexes: you are at -2 to defend against attacks from these hexes, and can only attack into those hexes with a Wild Swing. Everything else is a “back” hex and get no defense against attacks originating from these hexes!
