This question involves the complexity of ethics and military strategy. In military operations, the question of sacrificing a few innocent people in pursuit of a greater purpose is often referred to as a "utilitarian" debate. This view holds that if a certain action can save more lives or bring greater benefits overall, sacrificing some innocent people may be acceptable. However, this practice has also been subject to severe moral and legal criticism. International law, especially international humanitarian law, such as the Geneva Conventions, clearly prohibits attacks against civilians and unnecessary casualties. The lives of innocent people are considered inviolable. Therefore, although such considerations may arise in certain circumstances, the ethical and legal consequences of harming innocent people often make such choices extremely complicated. On the one hand, military commanders and decision-makers need to consider the overall war situation and strategic effects, and on the other hand, they also need to bear moral responsibilities and legal obligations to ensure the safety of innocent people. Ultimately, there is no simple answer to this question, and each specific situation requires in-depth ethical and legal analysis.
