In tabletop wargaming, positioning and movement are just as important as strategy and dice rolls, and this is especially true in Age of Sigmar. One of the core rules that players must understand early on is unit coherency. While it may seem like a simple restriction on how models are placed, unit coherency plays a major role in how armies function on the battlefield. It affects movement, combat effectiveness, and even survival of your units. For both beginners and experienced players, mastering unit coherency in Age of Sigmar can significantly improve gameplay and tactical decision-making.
What Is Unit Coherency in Age of Sigmar?
Unit coherency refers to the requirement that models within a unit must remain close to each other in a specific formation. This rule ensures that units behave as organized groups rather than scattered individuals.
In Age of Sigmar, each model in a unit must be within a certain distance of at least one or more other models in the same unit. The exact requirement can depend on the number of models in the unit.
Basic Coherency Rules
- Units with 2 to 5 models each model must be within 1 inch of at least one other model
- Units with 6 or more models each model must be within 1 inch of at least two other models
These rules prevent players from spreading their units too thin across the battlefield.
Why Unit Coherency Matters
Unit coherency is more than just a placement rule. It has a direct impact on how effective your army can be during a game. Maintaining proper coherency ensures that your unit remains functional and avoids penalties.
If a unit breaks coherency at the end of a turn, models that are not in compliance may be removed from play. This makes it crucial to always check positioning after movement, combat, and pile-in actions.
Key Reasons to Maintain Coherency
- Prevents loss of models
- Maintains unit effectiveness in combat
- Ensures proper use of abilities and buffs
- Keeps formations organized
Ignoring coherency can quickly weaken even the strongest units.
How Unit Coherency Affects Movement
Movement is one of the phases where coherency becomes most challenging. As units move across the battlefield, players must ensure that all models stay within the required distance.
This often means moving models in groups rather than individually. Careful planning is needed to avoid stretching the unit too far.
Movement Tips
- Move models in small clusters to maintain spacing
- Avoid long lines that can break easily
- Check distances after every move
- Use terrain as a guide for positioning
Good movement habits help maintain coherency without sacrificing tactical positioning.
Coherency During Combat
Combat introduces additional challenges for unit coherency. When models pile in or consolidate, their positions can shift quickly, increasing the risk of breaking formation.
Players must balance the need to engage enemies with the need to maintain proper spacing between models.
Combat Considerations
- Plan pile-in moves carefully
- Avoid overextending toward enemy units
- Keep track of model connections
- Re-check coherency after each combat phase
Maintaining coherency during combat can be the difference between holding a line and losing key models.
Strategies for Maintaining Unit Coherency
Experienced players develop strategies to maintain coherency while still maximizing their unit’s effectiveness. These strategies often involve careful positioning and awareness of the battlefield.
Common Strategies
- Use compact formations like circles or blocks
- Keep a central anchor model to guide positioning
- Move slower to avoid accidental gaps
- Practice measuring distances accurately
These techniques help ensure that units remain cohesive even in complex situations.
Common Mistakes Players Make
Many players, especially beginners, struggle with unit coherency. Understanding common mistakes can help avoid unnecessary losses.
- Spreading units too far apart
- Forgetting to check coherency after movement
- Overextending during pile-in moves
- Ignoring terrain obstacles that disrupt formation
Being mindful of these errors can improve consistency and gameplay performance.
Large Units vs Small Units
The size of a unit has a significant impact on how easy it is to maintain coherency. Smaller units are generally easier to manage, while larger units require more careful planning.
Small Units
- Easier to keep within range
- More flexible movement
- Less risk of breaking coherency
Large Units
- More difficult to maintain spacing
- Require tighter formations
- Greater risk of model removal if mistakes occur
Choosing the right unit size can influence how you approach the game.
Impact on Tactical Gameplay
Unit coherency directly influences tactical decisions in Age of Sigmar. Players must constantly balance aggression with control, ensuring that their units remain effective without breaking formation.
For example, spreading out to capture objectives may risk coherency, while staying tightly grouped may limit board control. Finding the right balance is key to success.
This dynamic adds depth to the game, making positioning just as important as combat strength.
Adapting to Different Scenarios
Different battle scenarios and objectives can change how players approach unit coherency. Some missions require spreading out, while others reward tight formations.
Scenario-Based Adjustments
- Objective control may require careful spacing
- Defensive play favors compact formations
- Aggressive strategies require controlled expansion
Adapting your approach based on the situation helps maintain coherency while achieving objectives.
Unit coherency in Age of Sigmar is a fundamental rule that shapes how the game is played. It ensures that units remain organized and balanced, adding an extra layer of strategy to movement and combat. By understanding the rules, practicing proper positioning, and avoiding common mistakes, players can maintain strong and effective units throughout the game. Mastering unit coherency not only prevents unnecessary losses but also enhances overall tactical performance, making it an essential skill for anyone looking to improve in Age of Sigmar.
