Which term describes the replacement of a unit by another?

• A. Retirement
• B. Delay
• C. Withdrawal
• D. Mobility

Answer: (A)

Replacement of one unit by another in an area of operation is best described by withdrawal. This term captures the outgoing unit pulling back while the incoming unit takes over, effectively swapping responsibilities. Retirement implies taking a unit out of service entirely, not simply swapping its duties. Delay means postponing action, and mobility refers to the capability to move—neither describes substituting one unit for another in the field.
