Permissive fire support coordination measures aim to _____ the attack of targets?

Permissive fire support coordination measures aim to facilitate the attack of targets. This is because these measures are designed to streamline and enhance the efficiency of fire support operations, ensuring that units can effectively engage targets with minimal restrictions. By clearly defining areas where fire support can be employed without needing additional approvals, permissive measures allow forces to focus their firepower effectively and achieve their objectives quickly.

In contrast, the other options either describe approaches that hinder or complicate the attack rather than support it. For instance, restrictive measures impose limitations that can slow down the process, whereas redundancy suggests duplicative efforts without increasing effectiveness. Thus, the focus on facilitation captures the intent of these measures to promote swift and effective target engagement.
