The purpose of this LSU NCBRT/ACE presentation is to provide an overview of observable attacker characteristics that may indicate an attack is part of a larger incident and a potential Complex Coordinated Terrorist Attack (or CCTA). There are several observable characteristics that may also include plans to overwhelm resources and make the attack as effective as possible. Recognition of these clues early in the attack will allow responders to activate appropriate assets and employ response resources as efficiently as possible.
