Context: A soldier's life in combat is an endless series of decisions that mean success or failure, and perhaps life or death for himself or his comrades. The rifleman crawling through the rubble of a bombed-out street must decide on the best moment to escape enemy fire as he dodges from one doorway to the next. He must take a chance. The general seeking to break an enemy defense line and destroy his forces must decide just when and how to strike and precisely to what extent he dare weaken one sector of his front in order to mass overpowering strength at the main point of attack. He, too, must take a chance, although, in the stilted phraseology of military communiqués, he calls it a "calculated risk".
"If his forces are united, separate them" is also interpreted: "If sovereign and subject are in accord, put division between them."
