All enlisted personnel are allowed to re-enlist for periods of:

• A. 4-6 years
• B. 3-6 years
• C. 1:1000
• D. 2-4 years

Answer: (B)

Reenlistment periods are the official lengths you can commit to when extending your service after the current enlistment ends. In the Coast Guard, the standard blocks available to most enlisted personnel span from three to six years. This range is broad enough to cover the common options that apply to all sailors, while shorter than three years or longer than six years aren’t universally offered or guaranteed. So, three to six years is the inclusive window that applies to all enlisted members. The other options either omit the minimum universal choice or suggest periods that aren’t generally available to everyone (and one option is not a valid time period at all).
