Lecture 7: Engineers at War
Lieutenant Colonel (Retd) Christopher Pugsley on "Engineers at War". Many of the most prominent man-made historical features in the landscape are the work of military engineers. Hadrian's Wall, Windsor Castle, the coastal fortifications, even the Albert Hall, all testify to the skills of the military engineer. Military engineers throughout history have always had to marry theory and genius to the practical skills of making the concept work in crisis on the ground; no small accomplishment.

1.2.3 Stage 1: Preparation

Numbers and diagrams are highly abstract and condensed summaries of the world. They require a degree of mental effort to bridge the gap between them and the aspects of the ‘real’ world they stand for. Approach them slowly and with care, allowing yourself time to get the feel of what you are looking at. Don't assume you already know what you are looking at.
