Weaponry equipment constitutes a vital foundation for military preparedness, and their environmental adaptability is of paramount importance.The geological environment, as a significant component of the natural environment for weaponry equipment, exerts notable influences on the performance, reliability, and service life of weapon systems, yet it has been overlooked in previous environmental adaptability studies. Based on the elucidation of the conceptual connotations of weaponry equipment environment and geological environment, this paper proposes the characteristics and trends of equipment environment that under joint warfare conditions. It explores the role and practical application of the geological environment in the development, navigation and guidance, mobility, firepower application, water supply, and maintenance of military equipment. Finally, by reviewing advancements in natural environment testing, environmental worthiness assessments, and environmental weapon development abroad, this paper presents three insights for the research and engineering practice of geological environment worthiness for weaponry equipment in China, aiming to facilitate the development of high environmental worthiness throughout the entire lifespan of equipment across all domains and contribute to the high-quality development of weaponry equipment.
