Art of War 11.33

This is rather a hard sentence on the first reading, but the key to it will be found, firstly, in the pause after 得, and next, in the meaning of 得 itself. The best equivalent for this that I can think of is the German “zur Geltung kommen.” Mei Yao-ch‘ên’s paraphrase is: 兵無强弱皆得用者是因地之勢也 “The way to eliminate the differences of strong and weak and to make both serviceable is to utilise accidental features of the ground.” Less reliable troops, if posted in strong positions, will hold out as long as better troops on more exposed terrain. The advantage of position neutralises the inferiority in stamina and courage. Col. Henderson says: “With all respect to the text books, and to ordinary tactical teaching, I am inclined to think that the study of ground is often overlooked, and that by no means sufficient importance is attached to the selection of positions ... and to the immense advantages that are to be derived, whether you are defending or attacking, from the proper utilisation of natural features.”
