The final personnel examples are Elizabeth Drake, an experienced plotter already working at Derby House when WATU formed, and Jean Laidlaw, a former Sea Ranger and chartered accountant. Their different backgrounds show the range of expertise the unit drew together. WATU also demonstrates how fragile the source base for institutional history can be: official tasks survive more clearly than daily experience because staff under wartime pressure did not always keep diaries, and families sometimes destroyed papers later. Continued secrecy may have made disposal seem responsible even when those records would now be valuable to historians. Losing personal testimony narrows both the analysis of the organization and the memory of the women who made it function.

Sparse diaries and destroyed family papers make the unit's daily pressures and participants' experiences difficult to reconstruct.
