The difference between investigation and reconnaissance

The difference between investigation and reconnaissance lies in the target and method.

Investigation refers to acquiring knowledge about a specific target by collecting intelligence and information, so as to make decisions or take actions. Investigation is usually aimed at specific targets, such as criminal suspects, hostile forces or intelligence targets. Investigation methods include investigation, surveillance, surveillance and evidence collection, aiming at obtaining detailed information and intelligence about the target. Reconnaissance refers to the observation and evaluation of geographical areas, hostile forces or battlefield environment in order to obtain tactical or strategic information. The goal of reconnaissance is usually to support military operations or war decisions. Reconnaissance means include the use of scouts, reconnaissance planes, satellites and other technical means, as well as covert observation, photography, measurement and other activities, aiming at obtaining information such as geographical environment, enemy situation and target position.
