Military Strategist Describes Israel's Secret Underground Tactic

About this video

Mike Ritland’s guest John Spencer, an expert on urban and subterranean warfare, explains why underground combat is one of the most under-resourced domains in modern military operations. Spencer describes how adversaries like Iran have moved critical infrastructure underground as surface warfare becomes more lethal, while the U.S. military lacks dedicated training, equipment, and doctrine for this environment. He recounts lessons from his Pentagon work on force design and argues that subterranean operations should be treated as a separate military domain, comparable to space or undersea warfare.

Key takeaways

• Spencer explains that underground warfare involves fighting below the surface and is as old as warfare itself, yet the U.S. military has no dedicated school or formal doctrine for it despite facing thousands of miles of enemy tunnels in conflicts from Vietnam to Gaza.
• According to Spencer, surface-level equipment like communications gear, night vision, and navigation systems fail underground, and specialized capabilities—like Israel’s Yahalom unit—are needed to operate effectively in confined subterranean environments.
• Spencer argues that adversaries are increasingly moving assets underground as surface warfare becomes more lethal, and he advocates for treating the subsurface as an independent military domain with its own force structure, budget, and research programs.
