• a memory storing at least one instruction;
• and
• at least one processor executing the at least one instruction,
• wherein the processor:
• identifies the target based on at least one of communication with a reconnaissance device linked to the target tracking device and vision data acquired through a camera included in the target tracking device, and performs a guidance process to approach the identified target,
• wherein, at a first tracking time point, the processor performs a first guidance process to track the target in a certain manner, and
• at a second tracking time point, which is chronologically subsequent to the first tracking time point, the processor performs a second guidance process to track the target in a manner different from the certain manner.
