In the context of GTA map markings, what does the triangle symbol '7-4-5' indicate?

The triangle symbol '7-4-5' in the context of GTA (Ground Tactical Area) map markings indicates a hospital. This marking is crucial for operational planning and navigation, as it helps pilots and ground forces quickly identify critical medical facilities in the area. Knowing the locations of hospitals can be vital for evacuations, medical support, and ensuring the care of wounded personnel.

In a tactical scenario, differentiating between various symbols used on maps is imperative for effective communication and situational awareness. While other symbols may represent control zones, landing zones, or observation points, understanding that '7-4-5' specifically denotes a hospital aids in mission planning where medical support needs to be prioritized or accessed quickly.
