Final answer:
In emergencies with high uncertainty and danger, proactive dispatch of personnel and equipment is sometimes necessary and historically supported, as seen with Korean field commanders acting without Tokyo's orders.
Step-by-step explanation:
When dealing with a major incident, the protocol for dispatching personnel and equipment can vary depending on the situation. Historically, there have been instances, such as field commanders in Korea dispatching reinforcements without any orders from Tokyo, where taking decisive action without formal requests has been supported by public opinion and proved to be strategic. In emergency situations, characterized by uncertainty and the potential for extreme physical danger, immediate response is often necessary to mitigate risk and save lives. Therefore, in contexts where rapid action could be critical, such as a serious fire, hazard, or combat situation, dispatching resources proactively can be a justified measure.
