司马穰苴 / Sima Rangju

司马穰苴 / Sima Rangju appears in 《资治通鉴·周纪》06丨魏文侯选谁当宰相呢（2） as a 齐国 military figure from the 春秋时期. The source says he had strong ability but low status, and that 晏婴’s recommendation to 齐景公 made his appointment possible.

The episode uses Sima Rangju as the first version of a military-management problem. It says “司马” is not his family name but an office title, then emphasizes that his command did not depend mainly on changing people or rewriting systems; it depended on military discipline, morale, and execution.
