Collection: Rules

The rules of Advanced Squad Leader (ASL) are complex and detailed, reflecting the game's focus on realistic tactical combat in World War II. The rules cover every aspect of gameplay, including movement, combat, morale, and terrain effects.

At its core, ASL is a turn-based game where each player takes a turn performing various actions with their units, such as moving, attacking, and rallying. The game is played on a hexagonal grid representing the battlefield, and each unit is represented by a counter with information about its combat capabilities, movement ability, and morale.

Movement in ASL is determined by a system of movement points, which are affected by terrain features and enemy fire. Units can move on foot or using various vehicles, such as tanks or trucks, each with their own unique movement capabilities.

Combat in ASL is resolved through a system of fire attacks and close combat. The outcome of each attack is determined by the attacker's firepower, the defender's defensive capabilities, and various modifiers such as range and cover. Morale is also an important factor in combat, as units may become demoralized or even rout under heavy fire.

The rules also cover a wide range of terrain features, such as hills, forests, and buildings, each with their own effects on movement, combat, and line of sight. Weather and environmental conditions can also play a significant role in gameplay, affecting movement and visibility.

The original Avalon Hill rules included Chapters A, B, C, D, J and part of H.  Others are added to by various modules which also include erratta pages which may be easily replaced as the rules are in a loose-leaf binder:
