Geographic Information System (GIS) and Remote Sensing have been considered significant in the military due to their spatiality in nature. In this study, the descriptive-analytical method was used to illustrate the applications of GIS in military operations, drawing lessons from land based military developments from selected studies. Recent military developments have seen various military institutions depending on reliable and accurate spatial mapping tools, for the purpose of Command, Control, Communication and Coordination in military operations. The study notes that high resolution satellite data and or drone technology integrated with machine learning and Artificial Intelligence (AI), have been utilized in the military for a variety of applications including cartography, terrain analysis, intelligence collection and dissemination, object recognition, safeguarding military vital installations, as well as historical construction. The integration of GIS machine learning and AI is of significance to the military planning and deployment, as the understanding of landscape is useful in determining strategic positions in the battle ground in real-time. The study recommends the need to train military personnel in geospatial techniques and ensure proper deployment, for fruitful military operations.
