In what environments do EOD technicians typically operate?

EOD technicians typically operate in land, sea, and air environments across various theaters of operation due to the nature of their mission. They are trained to handle and neutralize explosive devices in a wide range of settings, which can include military conflicts, humanitarian missions, and counter-terrorism activities. This versatility is essential as explosive threats can arise in diverse locations, including combat zones, naval operations at sea, and even aerial missions.

Operating solely in one environment, such as only on land during wartime or exclusively in urban settings, would severely limit their capability to respond to threats where they can appear. Additionally, focusing only on controlled training environments neglects the unpredictable and high-stakes scenarios that EOD personnel often face in real-world operations. Thus, the correct answer underscores the comprehensive training and operational readiness of EOD technicians across multiple environments.
