Previously, RFIs were sent to the ISRD for processing and prioritization.
It is often easier to task a CAS asset through the ASOC to support a short-notice operation than it is to prove to the ISRD that the raid in progress is a higher priority than servicing the ISR deck.
The UA can either self-designate the target, or another cell such as the ISRD or a JTAC, using a program called the Precision Strike Suite for Special Operations Forces, can pull mensurated or "sweetened" coordinates for precision-guided munition (PGM) engagement.
