contract-for-service

This revolutionary idea of Western citizenship__eplete with ever more rights and responsibilities__ould provide superb manpower for growing legions and a legal framework that would guarantee that the men who fought felt that they themselves in a formal and contractual sense had ratified the conditions of their own battle service.

That idea alone would eventually bring enormous advantages to its armies on the battlefield. (p. 122)
