6. HILLSIDE WALLS & HEDGES
6.1 A Hillside wall/hedge10 is one which lies along a hexside that is common to two adjacent hexes with different Base Levels, with none of the lower Base-Level's terrain appearing between the wall/hedge depiction and the higher Base-Level's terrain depiction. Examples of Hillside hedges are StX32-Y32 and ChK2-K3; an example of a Hillside wall is StS17-T16. All normal wall/hedge rules apply to Hillside wall/hedges except as modified herein.
6.2 LOS: A Hillside wall/hedge (including both its depiction and its associated hexside; B9.1) is ignored when determining whether or not a LOS exists between units whose elevations differ by ≥ one full level [EXC: a unit entrenched behind a Hillside wall/hedge still has its LOS restricted as per B9.21]. It is likewise ignored when determining the number of Blind Hexes created by a Crest Line. If a hill Crest Line ends at a Hillside wall/hedge, the line along which the hill depiction meets the wall/hedge depiction is considered to be the actual Crest Line.
6.3 ELEVATION, TEM & WALL ADVANTAGE: A Hillside wall/hedge is always at the higher of the two Base Levels it lies between, and is treated as a normal wall/hedge when calculating the TEM of targets at ≥ the wall/hedge's base elevation. However, a unit at any level lower than that on which a Hillside wall/hedge sits never receives any benefit (including Wall Advantage; B9.32) from that wall/hedge hexside. A unit in Crest status may claim Wall Advantage over a Hillside wall/hedge that forms a hexside of that unit's hex only if both are at the same elevation and on the same side of the Depression. Otherwise, a unit's inability to claim Wall Advantage over a Hillside wall/hedge hexside does not prevent it from claiming Wall Advantage over another wall/hedge hexside, provided the unit meets all the other B9 criteria for doing so.
EX: see the 6.2 illustration. Only squad F can claim Wall Advantage across hillside hedges T12-S12/T12-T11. Furthermore, squads C and E can never receive any benefit from the hillside hedges along hexsides(s) of their hexes, as the units are both lower than those hedges.
EX: The following serve to further illustrate various LOS possibilities with Hillside hedges/walls and slopes:
Squad A (whose Base Level elevation is Level 2) has a LOS to squads B, C, D, F, G and I. If squad A were entrenched, it would have a LOS to all squads except B, C, D, E and H.
Squad B (at Level 1) has a LOS to all squads except G (since G is not Up-Slope across hexside T12-T13).
Squad C has a LOS to all squads except H and I
Squad D has a LOS to all squads except G.
Squad E has a LOS to all squads except A and G.
Squad F has a LOS to all squads. If entrenched, it would have a LOS to all squads except B, D and H.
Squad G has a LOS to squads A, C, F and I.
Squad H has a LOS to squads B, D, E, F and I.
Squad I has a LOS to all squads except C (since squad I is not Up-Slope across hexside T12-U13).
