7.0 - Terrain

Any area of the battlefield that is not occupied by a terrain feature is referred to as the ground.

A terrain feature (or part of a terrain feature) that is mostly flat and shorter than ½” is considered part of the ground.

A terrain feature (or part of a terrain feature) that is not part of the ground is an obstacle. Obstacles come in 3 sizes: low, medium and high.

An obstacle (or part of an obstacle) that is less than 1” tall is a low obstacle.
An obstacle (or part of an obstacle) that is 1” or more tall but not taller than 1 ½” is a medium obstacle.
An obstacle (or part of an obstacle) that is taller than 1 ½” is a high obstacle.

Any part of an obstacle that overhangs, such as the arch of a doorway, is ignored.
