We are Legion

During the Shooting phase, the Daemon does not have to target all its ranged weapons against the same target. Instead, it may fire any of its weapons at a different target (declare all targets before rolling to hit). It can then choose to assault any of the enemies it has fired against.

If the Daemon is an Independent Character and joins a unit, it can choose different targets from its unit's. Note that the unit is not affected by the shooting of the character in regards to which enemy they can assault in the ensuing Assault phase.
