10.1 A Hillside wall/hedge 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 walls/hedges are 25B4-B5, 25C5-C6, 25U3-U4, 25V9-W9, 25X4-X5, 8M4-M5, 8X3-X4, 12X4-Y4, and 13S4-S5. All normal wall/hedge rules apply to Hillside walls/hedges except as modified herein.

10.2 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.

10.3 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: The 4-6-7 IN 25B4 can claim neither hexside TEM vs, nor Wall Advantage over, the 4-5-8 in B5, nor can it claim hedge TEM vs the 4-5-7 in C6; however, the 4-5-8 could receive such benefit, and the 4-5-7 could claim hedge TEM, vs the 4-6-7 because both British squads are directly behind, and at the same level as, a Hillside hedge (hexside C5-C6 in the case of the 4-5-7).

(If the 4-6-7 were in crest status with its center protected Crest hexside at B4-A5 or B4-B5, then it could, if having Wall Advantage, claim hedge TEM vs the 4-5-8/4-5-7 since it would be at the same level as, and directly behind, the hedge. If it claimed Wall Advantage it could not also claim entrenchment TEM vs the 4-5-8 [B9.31], but if it did not claim Wall Advantage while in crest status, the 4-5-7's attack vs it would still be affected by the B4-B5 hedge TEM [B9.3]. Regardless of whether or not the crest 4-6-7 claimed Wall Advantage, the 4-5-7's attack vs it would not be affected by entrenchment TEM [B20.92].

Neither the 4-6-8 IN C5 nor the Crest-status 4-4-7 in C5 can claim hedge TEM vs, or Wall Advantage over, the 4-5-7 because both German squads are lower than the C5-C6 hedge's base elevation. If the hero in B6 attacks the C5 Germans, the 4-4-7 (but not the 4-6-8) can claim the B5-C5 hedge TEM (B9.3). (The C5-C6 level-one hedge cannot affect that attack by the hero.)

Provided neither the 4-5-8 nor the 4-5-7 were already marked with a Wall Advantage counter the 4-4-7 could claim Wall Advantage over the B5-C5 hedge even though it cannot claim it over the higher-level C5-C6 hedge.

If the 4-5-8 fires at the Crest-status 5-4-8 in D5, the latter cannot claim hedge TEM since it is a level lower than hexsides C5-C6 and D5-C6.
