War technology has made remarkable leaps since howitzers lobbed shells at unseen enemy lines, sometimes hitting them, and bombs dropped from the air took out a target by razing entire city blocks, notes a new report in Joseph Farah’s G2 Bulletin.

Now, laser-guided sights can put a projectile literally through at building’s open window, and radio-guided bombs can hit a solitary rooftop in a compound of many buildings.

Other war technology similarly has radically improved communications, enemy observation, infiltration and other aspects of warfare.

But little has been done to advance underground warfare. After all, it’s been around for generations, and foot soldiers often started with trenches to hide themselves from the enemy and advanced to tunnels between trenches.

But that soon will change, as the U.S. government seeks technology that can be used in tunnels, caves, basements and anything else that’s below ground.

“In many ways, subterranean environments have remained an untapped domain in terms of developing breakthrough technologies for national security,” said Timothy Chung, program manager in the Tactical Technology Office at the Defense Advanced Research Projects Agency.

“We’re looking for audacious ideas on how to overcome the multi-faceted challenges these locations present – poor visibility and communications, difficult access, and unpredictable terrain among them – and provide previously unimaginable capabilities for warfighters and emergency responders.”

The TTO said it is now looking for ideas “to augment its understanding of state-of-the-art technologies that could enable future systems to rapidly map and navigate unknown complex subterranean environments.”

The federal agency explains: “Subterranean warfare – whether involving human-made tunnels, underground urban infrastructure, or natural cave networks – has been an element of U.S. military operations from World War II and Vietnam to Iraq and Afghanistan. As above-ground commercial and military intelligence, surveillance, and reconnaissance capabilities continue to grow more capable and ubiquitous, adversaries are increasingly heading underground to circumvent detection.”
