Train as you fight. It’s the first of the Army’s ten principles of training, meant to ensure that the Army will develop and execute tough, realistic training. As long as we train as we fight, no soldier should confront a situation or an environment for the first time in combat. Unfortunately, the Army occasionally ignores this principle. Case in point: despite history and global urbanization trends, the Army doesn’t adequately train for operations in urban environments. It is time that changed. The Army needs to establish an urban warfare school to prepare soldiers to fight and survive in dense urban terrain.
