Even if the Khan isn't first, he is. the Mongols are always the exception. Also Rommel and WWII was too big for luck to play any major factor at any period. WWII Germany had a messy, incredibly competitive command structure; too many projects to fund properly; a distinct lack of key resources; and inefficient production and logistics, which had severe consequences when the extensive pre-war preparations didn't result in the short, crushing victory they needed. The German command structure was mostly fixed, but too late to do anything but prolong the Reich's demise. Most of this I learned from youtube channels like Military Theories visualized and Bismarck. The Reich was damned near destined to lose after it didn't immediately win.
