Thanks Nick,
The main article is "The GI in Heroes of the Nam, A short history of units and tactics"
In section titled "Basic Tactical Concepts", it gives four examples the Figures for which just don't match with the text or scenario being described. Example "In Firgure 1 Lt. Jenson leads...." Figure 1 actually shows Lt Diem and some VC squads. And so on for Figures 2 to 4 - the text and picture just don't match up.
Cheers,
Doug
