Subterranean warfare U.S. Army leaders say the next war will be fought in mega-cities, but the service has embarked on an ambitious effort to prepare most of its combat brigades to fight, not inside, but beneath them. Late last year, the Army launched an accelerated effort that funnels some $572 million into training and equipping 26 of its 31 active combat brigades to fight in large-scale subterranean facilities that exist beneath dense urban areas around the world. Jason Dempsey, an adjunct senior fellow at the Center for New American Security, was skeptical about the scale of the program. Dempsey, a former Army infantry officer with two tours in Afghanistan and one in Iraq, told Military.com that such training "wasn't relevant" to fights in Iraq and Afghanistan.  He questions spending such a large amount of money training and equipping so many of the Army's combat brigades in a type of combat that they might never need. ]https://taskandpurpose.com/.amp/news/army-subterranean-warfare-training?__twitter_impression=true
