Belgian Blood Variant
Two minor rule changes speed up the game considerably -
Planes can attack enemy zones, even if they cannot return to a friendly zone after combat.
Planes that cannot return are destroyed after combat.
(They crash, like in a kamikaze attack.)
Transport ships can form a bridge between two land zones and connect these zones.
Any number of infantry and/or tanks can use this “bridge”.
Crossing the bridge takes full movement; tanks will not be allowed to blitz.
(This speeds up the game incredibly and gives Germany an edge when the game starts.)
