Answer:
A. All volunteer army is the correct answer
Step-by-step explanation:
Draft conscription was used by Nixon administration to get solders for Vietnam war.
Military conscription has been used many time in USA. Draft was abolished in 1973 but the men of draft age were asked to register with the selective service system so that a draft could be prepared if needed.In the Vietnam war, two third of the American troops were volunteers and the others were selected through draft. Secret service system used to call the men of draft ages and evaluated their draft status. These board had enormous power to who would go to the war and who wont. The members were pressurised by families to exemption for their relatives. The men of poor families were and the working class were mistreated and had no exemptions from the draft. Very few soldiers were from upper class families. So, all volunteer army cannot be considered as Nixon's Vietnam war policy.
