**Tank Commander** is a simple table-top game where two players take turns to shoot at each other's tanks. The game is played on a hexagonal grid, and each player has a tank that can move and shoot in six directions. The simplest goal of the game is to destroy the opponent's units.
Players take turns activating a unit, performing a number of actions with it, and then ending their turn. The game is over when one tank is destroyed.
Players take turns activating a unit, performing a number of actions with it, and then ending their turn. The battle is over when the mission is complete, or a player concedes, or after 10 turns of play.

The basic tank starts with the following stats:
| Armor | Movement | Accuracy | Hull Points | Actions |

- **Forest**: When a tank is in or behind a forest space, enemy accuracy is -1.

### Advanced Play
#### Air Strike
Mark a space anywhere on the board. In the next turn, the player must roll a 6+ for the air strike to hit. On the following turn, it's a 5+, and then 4+, and so on. An air strike is never called on a roll of a 1.
When an air strike is carried out, the marked space is hit with an AT round with a strength of 6. Roll a die to determine the direction of the blast (1 is north, 2 is northeast, and so on). Then roll a die to determine the distance of the blast (1 is 1 space, 2 is 2 spaces, and so on). Each of those spaces are also hit with an AT round with a strength of 6.
#### Infantry
### Infantry
Some battles may include infantry units. Infantry units can move 2 spaces, and can fire at tanks within 2 spaces. Infantry units have an armor value of 2, and a hull point value of 1. Infantry units can be destroyed by a hit from any main gun, or by an Anti-Infantry Weapon. Infantry can't be targeted if they are in an adjacent space to a friendly tank.

#### Missions
### Air Strikes
Mark a space anywhere on the board. In the next turn, the player must roll a 6+ for the air strike to hit. On the following turn, it's a 5+, and then 4+, and so on. An air strike is never called on a roll of a 1.
When an air strike is carried out, the marked space is hit with an AT round with a strength of 6. Roll a die to determine the direction of the blast (1 is north, 2 is northeast, and so on). Then roll a die to determine the distance of the blast (1 is 1 space, 2 is 2 spaces, and so on). Each of those spaces are also hit with an AT round with a strength of 6.
### Missions
Playing to destroy your enemy is only one way to play Tank Commander. Missions can be created to add objectives to the game. Some examples of missions include:
- **Capture Objectives:** Use infantry to capture 1, 2 or 3 spaces on the board
- **Breakthrough:** Move a tank to the other side of the board to win. One player is the attacker, the other is the defender.
- **Basic Training:** One tank driving to spaces and shooting targets, to learn basic rules.
- **Skirmish:** 1-vs-1 tank battle with light terrain.
- **Capture Objectives:** Use infantry to capture 1, 2 or 3 spaces on the board.
- **Breakthrough:** Move your tank to the other side of the board to win. One player is the attacker, the other is the defender.
- **Destroy Target:** Destroy a specific target on the board. The target can be a building, a tank, or an infantry unit.
- **Escort:** Move an infantry squad across the battlefield alive.
- **Beach Landing:**
- **Urban Warfare:** Navigate tank columns through a maze of streets to take the town's central plaza.
- **Cross Minefield:** Navigate across a minefield with infantry disabling mines.
- **Disable AA Guns:** 3 air strikes available for free, but they fail on 2+ while 3 AA guns are intact. Destroy those guns and call in support.

#### More Questionable Ideas
- **Weather:** Roll a die at the beginning of each turn. On a 1, a storm hits. All tanks have -1 accuracy, and all infantry have -1 movement.
- **Night Fighting:** Accurancy is lowered, range is lowered. Tanks can fire flares to light up parts of the battlefield for both sides.
- **Campaign Progressions**: Players can keep track of their tanks and crew from battle to battle. Crew members can gain experience, and tanks can be upgraded with new equipment.
- **Hover Tanks, Walkers, etc.**: Add new units to the game with different movement and armor values.
