What is the primary risk when transmitting near UXO?

When transmitting near unexploded ordnance (UXO), the primary risk is indeed a safety hazard. UXOs are munitions that did not detonate as intended during military operations and pose a significant threat to personnel and equipment if disturbed or inadvertently triggered. The safety hazard associated with UXO is paramount because it can result in severe injury or death if the ordnance is activated during the operation.

While other risks such as battery depletion, radio malfunction, and signal interference may be considerations in different contexts, they do not encompass the immediate life-threatening danger posed by UXO. Ensuring personnel safety is the foremost priority in military operations, especially in areas where UXO may be present, making the identification and avoidance of potential hazards vital in planning and executing communications tasks.
