What are the main steps in the terrorist attack progression?

The main steps in the terrorist attack progression typically include phases that focus on creating a clear pathway from the initial concept of an attack to its execution. The selected answer outlines a logical sequence beginning with identifying potential targets, which is crucial for any attacker deciding whom or what to target. Following that, conducting surveillance is essential for understanding the target's security measures, patterns, and vulnerabilities. This phase helps attackers gather the information needed to effectively plan their action.

Once sufficient information has been obtained, targeting selection is undertaken, where attackers make definitive choices about which specific targets to strike based on their assessments. Finally, the attack is executed. This structured progression from considering options to actual execution reflects the methodical approach that is often employed in planning an attack, highlighting the emphasis on research and strategy prior to any violent action.
