Napoleon had always aimed at his version of shih, and he perfected it in the 1805 campaign. Obsessed with structure and organization, he developed the corps system, building flexibility into the very skeleton of his army. The lesson is simple: a rigid, centralized organization locks you into linear strategies; a fluid, segmented army gives you options, endless possibilities for reaching shih. Structure is strategy—perhaps the most important strategic choice you will make. Should you inherit a group, analyze its structure and alter it to suit your purposes.
