I want to know the answer to the following question:
Gunlaying radar and RAF controls combined to create what system?
All the background I'm provided with is that "Of greater potential was the GL (Gunlaying) radar and searchlights with fighter direction from RAF fighter control rooms to begin a GCI system (Ground Control-led Interception) under Group-level control (No. 10 Group RAF, No. 11 Group RAF and No. 12 Group RAF).". Is that enough to answer the question?
