Overview: “Explosive Ordnance Reconnaissance” could refer to surveying activities specifically aimed at identifying and assessing explosive ordnance or potential explosive threats in a given area. This would involve searching for and locating explosive devices or unexploded ordnance and gathering information about their type, condition, and potential danger.
It’s worth noting that while the term “Explosive Ordnance Reconnaissance” is not widely recognized or used, the concept of conducting reconnaissance activities to identify explosive hazards is an integral part of broader explosive ordnance disposal (EOD) operations.
