36.1 Prepared Fire Zone (PFZ) counters are placed prior to setup by the side that has been assigned PFZ factors per scenario OB.21
36.2 PFZ CREATION: PFZ factors may be "spent" to create a PFZ by converting certain types of terrain within the purchaser’s setup area into Vineyard-(12.7)/
36.21 A woods, Forest, pine woods, Light Woods, jungle, or bamboo hex may be permanently converted into a vineyard hex at a cost of one PFZ factor, and is indicated by the placement of a PFZ Vineyard counter in the hex. Deep Snow (E3.73) does not transform a PFZ Vineyard into Open Ground and a converted jungle hex is still treated as a jungle hex for G7.1 purposes.
36.22 A brush, vineyard (including such converted per 36.21), orchard, cactus patch, olive grove, grain, palm tree, or kunai hex may be permanently converted into an Open Ground hex at a cost of one PFZ factor, and is indicated by the placement of a PFZ Open Ground counter in the hex.
EX: A scenario provides a player with four PFZ factors. He may convert four woods hexes into four vineyard hexes, or three woods hexes into two vineyard hexes and one Open Ground hex or he can convert two woods hexes into two Open Ground hexes.
EX: Using board 42, the Finnish player has received 4 PFZ factors and spent them placing one PFZ (OG) counter in X6 (1 factor) and one in W7 (2 factors) and a PFZ (Vineyard) counter in V6 (1 factor). When the Russian 6-2-8 moves into hexes V7, U7, and V6, fire from the Finnish 4-4-7 will incur the following DRM: vs V7 -1 (-1 [FFNAM]), vs U7 +2 (-1 [FFNAM] +1 [TEM] +2 [Hindrance in W6 and V6]), and vs V6 0 (-1 [FFNAM] +1 [Hindrance in W6]).
36.23 GULLIES & STREAMS: The appropriate terrain in a gully/
36.3 PATHS & ROADS: A PFZ counter eliminates any paths (13.6 and G.1) in the hex, but all playable roads still exist as depicted in the hex.
36.4 WALLS, HEDGES, & BOCAGE: Wall, hedge, and bocage hexsides of converted hexes still exist and are unaffected by the placement of a PFZ counter.
36.5 WATER OBSTACLES: All Water Obstacles (e.g., hexside ponds) in a converted hex still exist and are unaffected by the placement of a PFZ counter.
