What is the defining feature of a hasty defensive position?

A hasty defensive position is characterized primarily by its rapid establishment in direct response to an imminent threat. The defining feature is the need to act quickly, often to provide immediate protection and support to troops or equipment that may be under attack or vulnerable. This type of position does not involve elaborate planning or permanent construction; instead, it is designed for quick setup using available resources.

While options involving permanent construction, utilization of advanced technology, and extensive planning indicate more structured and secure defensive operations, they do not align with the essence of a hasty position, which must be adaptable and set up under time constraints. Thus, the focus on immediacy and responsiveness is what truly defines a hasty defensive position.
