"Bs Attack (Guided)" allows to make a Bs Attack against troopers in targeted state. In N5 you have to use rangeband modifiers instead of the +6 mod of N4. Does the Targeted state's +3 mod also apply? I cannot find anything that says otherwise, but in N4 it defiantly did not.
Yes. The example of guided attacks in the wiki includes the +3 bonus for Targeted: https://infinitythewiki.com/BS_Attack
