Army Is Spending Half a Billion to Train Soldiers to Fight Underground
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.
For this new type of warfare, infantry units will need to know how to effectively navigate, communicate, breach heavy obstacles and attack enemy forces in underground mazes ranging from confined corridors to tunnels as wide as residential streets. Soldiers will need new equipment and training to operate in conditions such as complete darkness, bad air and lack of cover from enemy fire in areas that challenge standard Army communications equipment.
