What are the three detection countermeasures for mines and booby traps?

The three detection countermeasures for mines and booby traps are visual, probing, and electrical.

Visual detection involves carefully observing the environment for any signs of mines or booby traps, such as unusual patterns in the terrain or disturbed soil. This method relies on the ability to spot indicators that something may be hidden just below the surface.

Probing is a technique where a tool is used to physically search the ground to detect the presence of mines or booby traps. This involves using a long stick or probe to feel for variations in resistance that indicate an object buried beneath the ground.

Electrical detection employs devices that can use magnetic, electromagnetic, or other electrical methods to detect explosive devices. These technologies can identify the components of mines based on their conductive or reactive properties, providing an effective means for finding them without coming into physical contact.

These methods are essential for safely navigating areas that may be contaminated with explosive devices and are widely taught in military training to ensure the safety of personnel. The other choices do not represent established methods specifically for detecting mines and booby traps, which is why they are not suitable options.
