And They Shall Know No Fear Space Marines automatically pass tests to regroup, and can take such tests even if the squad has been reduced to less than half strength by casualties, though all other criteria apply. Usually troops that regroup cannot move normally and always count as moving whether they do or not, but these restrictions do not apply to models subject to this special rule. If Space Marines are caught by a sweeping advance, they are not destroyed and will instead continue to fight normally. If this happens then the unit is subject to the No Retreat! rule in this round of close combat and might therefore suffer additional casualties.
Units which include Servitors are still subject to this rule, providing that the unit contains at least one Space Marine.
Combat Squads A number of ten-man units in the Space Marines army have the option of breaking down into two five-man units, called combat squads. The decision to split the unit into combat squads, as well as which models go into each combat squad, must be made when the unit is deployed. Both combat squads can be deployed in separate locations. The one exception to this is a unit that arrives by Drop Pod. The player can choose to split such a unit into combat squads when it disembarks from the Drop Pod.
If you decide to split the unit into combat squads, then each combat squad is treated as a separate unit for all game purposes from that point.
Jump Infantry Jump infantry can use their jump packs (or equivalent) and move up to 12" in the Movement phase. This is optional and they can choose to move as normal infantry if they wish. When using jump packs, they can move over all other models and all terrain freely. However, if a moving jump infantry model begins or ends its move in difficult terrain, it must take a dangerous terrain test. Jump infantry models may not end their move on top of other models or impassable terrain, except that they can end their move on top of impassable terrain if it is actually possible to place the models on top of it. If they do that, however, they treat the impassable terrain as dangerous terrain. All jump infantry units may enter the battle by ‘deep strike’.
Jump infantry fall back 3D6", because they always use their jump packs when doing this. They move over any terrain and models when falling back, but if they end their move in difficult terrain (or on top of flat impassable terrain) they must still take a dangerous terrain test. They cannot end their move on top of other models, and must alter the direction of their fall back move as little as possible in order to avoid them, just as a normal unit would when falling back on foot. If they cannot do this, they are trapped and destroyed.
Jump infantry assault 6" like normal infantry. This move is slowed by difficult terrain in the same way as other infantry, because the unit always covers the last few yards of an assault on foot.
