What military time does 6:00 PM equate to?

In the 24-hour clock system, which is commonly used in the military, time is expressed in hours ranging from 0000 (midnight) to 2359 (one minute before the next midnight). To convert standard time to military time in the PM hours, you add 12 to the hour.

For 6:00 PM, you take the hour (6) and add 12, resulting in 18:00 or 1800. This makes B the correct answer, as it correctly represents the military time for 6:00 PM.

The other choices represent different times of day; for instance, 1700 corresponds to 5:00 PM, 1900 is 7:00 PM, and 2000 is 8:00 PM, which are not applicable for 6:00 PM. Understanding this conversion is essential for effective communication and scheduling within military operations.
