Most existing approaches to assessing ecosystem sustainability focus on natural ecosystems and their resilience to infrequent natural extreme events. However, the stability of ecological systems under military-technogenic impacts during hostilities presents a unique challengeyiv. These impacts are not inherent to natural environments but arise from complex mechanical, physical, and chemical factors associated with the use of destructive military means and equipment on the battlefield. A critical dimension of this interaction lies in the dual nature of ecosystem stability. On one hand, it reflects the ecosystem’s capacity to endure external military-technogenic pressures. On the other hand, resistance to specific military-technogenic factors indicates the ecosystem’s safety from those impacts. This duality extends the concept of ecosystem sustainability into the military-technosphere, emphasizing environmental safety during hostilities. While interconnected in terms of preserving natural biota in operational and affected zones, the concepts of ecosystem sustainability and environmental safety each serve distinct purposes. This study examines ecosystem sustainability by quantifying permissible military-technogenic loads required for ecosystem preservation. It also investigates the causal relationships underlying the formation of these loads to identify technological approaches that maintain biologically determined thresholds for specific military-technogenic factors. These findings contribute to advancing the understanding of ecological resilience and safety in conflict-affected areas.
