What distinguishes the 'pieing' technique from merely looking into a room before entry?

The 'pieing' technique is distinguished from merely looking into a room before entry by its methodical, controlled, and segmented visual assessment, designed to minimize exposure and maximize information gathering. Simply looking into a room typically involves a quick glance, which can be incomplete and expose the viewer to potential threats. Pieing, on the other hand, involves slowly and deliberately exposing small sections of the room to view, moving incrementally from one side of the entry point to the other, like slicing a pie. This allows for a systematic assessment of potential threats while minimizing the amount of the body exposed at any given time. Each small movement reveals a new section of the room, allowing for a more comprehensive and safer assessment. For example, instead of stepping directly in front of a doorway and looking into a room, pieing involves staying behind cover and slowly exposing one small section of the room at a time, identifying potential threats before fully committing to entry. This systematic approach minimizes the risk of surprise and allows for a more informed decision regarding entry tactics.
