Rules (6) And They Shall Know No Fear A unit that contains at least one model with this special rule automatically passes Fear and Regroup tests. When it Regroups, the unit does not make the 3" Regroup move, but can instead move, shoot (or Run) and declare charges normally in that turn. Furthermore, if a unit containing one or more models with this special rule is caught by a Sweeping Advance, they are not destroyed, but remain locked in combat instead. Combat Squads A full strength, ten-man unit with this special rule can break down into two five-man units, called combat squads, considered to be two five-man squads of the same type. For example, a ten-man Tactical Squad can split into two five-man Tactical Squads using the Combat Squads special rule.
You must decide which units are splitting into combat squads, and which models go into each combat squad, immediately before determining your Warlord Traits. A unit split into combat squads therefore is now two separate units for all game purposes, including calculating the total number of units in the army and determining the number of units you can place in reserve. Then proceed with deployment as normal. In an exception to the normal rules, two combat squads split from the same unit can embark in the same transport vehicle, providing its Transport Capacity allows. Once you have decided whether or not to split a unit into combat squads, it must remain that way for the entire battle. It cannot split up or join back together later on in the battle, nor can you use a redeployment to split up a unit or join it back together.
Note that Bike Squads count as being at full strength when they have eight Space Marine Bikers and one Attack Bike. If split into combat squads, one combat squad will have five Bikers, the other will have three and the Attack Bike. Chapter Tactics When choosing an army, all models in the same Detachment or Formation must be drawn from the same Chapter. If a unit's datasheet contains a Chapter in brackets after the Chapter Tactics special rule - for example, "Chapter Tactics (Ultramarines)" - the unit must always be drawn from this Chapter, and therefore cannot be included in a Detachment or Formation with any units that are drawn from other Chapters. All models drawn from a given Chapter benefit from that Chapter's Special Rule. If a unit contains models drawn from two different Chapters, it counts as from neither Chapter, and thus benefits from neither Chapter Tactic. Bulky Bulky models count as two models for the purposes of Transport Capacity. Slow and Purposeful A unit that contains at least one model with this special rule cannot Run, Turbo-boost, move Flat Out, perform Sweeping Advances or fire Overwatch. However, they can shoot with Heavy, Salvo and Ordnance weapons, counting as stationary even if they moved in the previous Movement phase. They are also allowed to charge in the same turn they fire Heavy, Ordnance, Rapid Fire or Salvo weapons. Deep Strike Deep Strike Mishap Table: D6 Roll
1: Terrible Accident! - The entire unit is destroyed!
2-3: Misplaced - Your opponent may deploy the unit anywhere on the table (excluding impassable terrain, but including difficult terrain, which of course counts as dangerous for Deep Striking units), in a valid Deep Strike formation, without rolling for scatter. Units embarked on a misplaced Transport can disembark during their Movement phase as normal.
4-6: Delayed - The unit is placed in Ongoing Reserves.
