This is an interesting research paper:
The factors that threaten an army’s equanimity when it comes to fighting in an urban environment are the same for all belligerents. They do not impact regular Western soldiers more than irregular, non-Western challengers, who are thought to be unaffected by, or even gain an advantage from, these factors. This thinking comes from an entrenched mindset that insists on the uniqueness of the urban environment and holds firmly to certain shibboleths about urban warfare that are equivocal, if not outright ahistoric. The better trained and better equipped soldier should be comfortable in the chaos of the city — or at any rate as comfortable as he or she would be in any other environment. This is true not only for confrontations between regular and irregular forces, but also for “near-peer” conflict. The advantages afforded to the better trained, equipped, supported, and mentally prepared soldier are magnified by this environment, which rewards tactical skill.
