Operation JUST CAUSE provided the U.S. military its first significant experience in urban operations since the Vietnam War. This operation took place in Panama in December 1989, where U.S. forces engaged in complex urban combat scenarios to oust General Manuel Noriega from power. The operation required soldiers to navigate densely populated areas, confront issues related to civilian safety, and employ tactics suited for urban landscapes, showcasing the challenges and intricacies faced when operating in city environments. This was a pivotal moment, as lessons learned during this operation would influence U.S. military strategy and tactics in subsequent urban conflicts.
