tunnel network
Subterranean connected pathways
A tunnel network is an interconnected system of underground passages.
The term appears in military contexts for defensive or smuggling infrastructure: Hamas operates an extensive tunnel network beneath Gaza.
It also describes transportation systems: London's tunnel network moves millions daily.
Animals create tunnel networks too—moles, prairie dogs, and ants excavate elaborate subterranean passage systems.
