Furious Charge Models with the Furious Charge special rule issued with a Charge Order add 2 to any Fight roll they make instead of 1 when issued with that Order, so long as they have moved at least 1" during the preceding Movement phase.
Independent Models with the Independent special rule function with a greater degree of autonomy. All models with this special rule and the same name within a Detachment form an "Independent Unit". A Detachment can have multiple Independent Units within it, with each Independent Unit consisting of models of the same name. The remaining models (i.e., those without the Independent special rule) are referred to as the "Detachment Core".
All models within an Independent Unit must maintain a 2" Detachment Coherency with other models in the same Independent Unit and a Detachment Coherency of 6" with the Detachment Core - at least one model from each Independent Unit must remain within 6" of one or more models from the Detachment Core.
If the controlling player wishes, each Independent Unit may be issued its own Order during the Order phase - this can be a different Order from the rest of its Detachment. In addition, models within the Independent Unit may choose a different target than the rest of their Detachment when firing - all models within an Independent Unit must fire at the same target unless specified otherwise.
Though it has its own Order, the Independent Unit is still part of the larger Detachment, and thus activates and reveals its Order at the same time, is issued with a Fall Back Order if the Detachment is, etc. If the Detachment calls an Overwatch, an Independent Unit only discards its Advance Order or First Fire Order if one of its models fired during the Overwatch, not if other models from the Detachment did so.
A Detachment that contains one or more Independent Units is only considered to be Engaged if a model without the Independent special rule is Engaged. If one or more models with the Independent special rule are Engaged, then all models within that Independent Unit are also Engaged, however the larger Detachment can still act as normal, providing they maintain Detachment Coherency. In other words, an Independent Unit and its Detachment count as two separate Detachments for the purposes of determining Combats and determining which models are Engaged.
Models with the Independent and Deep Strike special rules may start the game in Reserve even if the larger Detachment is deployed on the battlefield - all models in an Independent Unit must be deployed in Reserve if one is. When the Independent Unit arrives via Deep Strike, it must be deployed within 6" of one or more models from the larger Detachment (i.e., within Detachment Coherency). The Independent Unit does not scatter, but must follow all other rules related to Deep Striking. If all other models from the Detachment have been destroyed before the Independent Unit has Deep Striked, then it is placed as if it were a normal Deep Striking Detachment.
