Where should a warning device ideally be attached to avoid detection by the enemy?

Attaching a warning device where natural vegetation will conceal it is ideal because it provides effective camouflage, making it less visible to enemy forces. Natural vegetation can effectively break up the outline of the device and blend it into the surrounding environment, thereby reducing the likelihood of detection. This concealment is crucial for maintaining the element of surprise and ensuring that the warning device serves its purpose without giving away the position or intentions of friendly forces. Locations with dense foliage, trees, and shrubs are particularly beneficial for hiding such devices, allowing them to alert forces without compromising operational security.
