I propose showing the approximate communication range to all same-faction players. Hovering over a base or command truck should display the communication radius, as shown in my screenshot, so players can tell if they are fighting within coverage.

A toggle for persistent range display would also help, keeping the radius visible without hovering over base icons. Overlapping communication areas can render like my second image for a neat, functional look, eliminating constant mouse checks.

This also allows commanders to instantly identify communication dead zones and strategically valuable spots for bases. Base counts appear to be limited, so precise planning is needed to fully secure all locations while avoiding base placement limits.
