What is meant by 'elapsed time' in military terms?

In military terms, 'elapsed time' typically refers to the duration between departing from one duty station and arriving at another. This encompasses the total time taken during the transition, including travel and any potential delays. It is crucial for planning and coordination, especially in logistics and personnel movements, as it impacts operational readiness and scheduling.

The other options, while related to time management in a military context, do not capture the specific definition of 'elapsed time.' The first option focuses on the duration required for completing a task, which is more task-oriented rather than encompassing travel time. The second option addresses leave time, which pertains to personal time away from duty rather than travel. The last option, related to transportation, might seem close but doesn't accurately define elapsed time, as it lacks the full context of the time from departure to arrival, including all aspects of the journey.
