Commencing in the early 1990s, Mr. James O'Bryon of the Office of the Secretary of Defense (OSD), Operational Testing and Evaluation (OT & E), charged the Vulnerability Lethality Division (VLD) of what is now the U.S. Army Research Laboratory (ARL) to capture in a hard-bound book the art/science of vulnerability and lethality (VIL) analysis. This work has since expanded into the publication of a series of volumes, each dedicated to a particular portion of the VIL community-ground mobile targets, hardened fixed targets, aircraft, etc. As a first step in this mammoth effort, a number of articles were commissioned to be gathered from some of the giants in the history of VIL analysis. These articles gave a foundation from which the writing of the first of the series commenced and are collected in this report with the hope that future generations of VIL analysts will find in them inspiration for their own accomplishments.
