NWars:Forest

Forest is a type of terrain in all installments of the Nintendo Wars series.

Purpose
Forest terrain slows down vehicles, but in return provides good defense boosts. It is fairly common, being less extreme than mountains while still giving stronger variety to maps.

The defense boost is strongest in Game Boy Wars 3; even with the increased influence of high damage attacks, reducing an attack's damage by 2 full HPs is still more effective than using the equivalent of 2 Terrain Stars in Advance Wars.

Forest is one of the two types of terrain in Famicom Wars that gives a stronger defense boost to foot soldiers than vehicles, the other being Plains.

A Forest tile can be removed by either the Constructor or the Strategic Bomber, but it is impossible to make Forest tiles with either unit. Careful thought is required before touching Forest tiles.

In the Advance Wars series, a land unit sitting on a Forest can't be detected by the enemy force unless there's an enemy unit adjacent to the tile.
