Basics

Green Men, Grey Tanks is a tactical hex-based game. Control your units, capture flags, and outwit your opponent.

Movement

Select a unit to see its range. Click a highlighted hex to move. Terrain affects speed.

Combat

Select adjacent units and click an enemy to attack. Combat depends on odds and a dice roll (d6).

Zone of Control (ZOC)

Every unit exerts a ZOC over its six adjacent hexes. ZOC represents the area the unit can influence with its fire.

• Movement: Entering an enemy ZOC hex ends the unit's movement immediately. You can move out of a ZOC, or from one ZOC into another, but the unit must always stop in the new ZOC hex.
• Rivers: ZOC does not extend across river edges. You can move freely next to an enemy if there is a river between you.

Supply

Units need a supply line to their side's supply sources (marked with dashed borders) to operate at full efficiency. Supply travels through roads or open terrain.

Blocking Supply: Supply lines are blocked by enemy units and their ZOC. However, a friendly unit occupying a hex negates the enemy ZOC for supply purposes in that hex.

Out of Supply (OoS) Effects:

• Combat: Both Attack and Defense strengths are reduced by 1/3 (multiplied by 2/3).
• Movement: Heavy units (Tanks) have their movement range reduced by 1/3. Infantry movement is unaffected.

Terrain Effects

*Roads reduce movement cost to 0.5 points. Crossing a river edge costs an extra +1 point. Attacking across a river reduces attacker strength by 1/3.

Unit Types

Artillery

Artillery is a long-range support unit with unique rules:

• Range: Artillery attacks at exactly 2 hexes distance. It cannot attack adjacent (range 1) targets.
• No attacker loss: Artillery never suffers damage as the attacker — attacker casualties from combat results are ignored for artillery.
• No advance: When artillery destroys an enemy unit, it does not advance into the vacated hex.
• Rivers: River edges do not reduce artillery's attack strength.

Tank Breakthrough

A tank that destroys an enemy unit and advances into the vacated hex earns a Breakthrough: its attacked flag is reset, allowing it to attack again this turn. Each tank can use breakthrough only once per turn.

Victory & Scoring

The game is won either by wiping out all enemy units, or by having the most points when the turn limit is reached. Points are awarded for the following achievements:

• Destroying an enemy Tank: 2 points
• Destroying enemy Infantry or Artillery: 1 point
• Owning a City: 3 points (awarded at the start of the game if owned, or upon capture. Points are lost if the city is lost)
