What aspect does NOT typically require adjustment in subsequent fire commands?

The choice indicating that the firing position does not typically require adjustment in subsequent fire commands is correct because, once established, the firing position generally remains constant for the duration of a mission or engagement. The machine gun crew selects a firing position based on operational factors like cover, concealment, and the overall tactical plan.

While the direction and elevation of fire must often be adjusted based on target movement or changes in the battlefield, and the rate of fire can vary depending on ammunition expenditure or tactical requirements, the initial firing position is set to provide a stable platform from which to engage targets. Similarly, the termination of fire may change as the situation evolves, but the physical location from which the gunner is firing typically remains unchanged throughout engagements unless there is a need to reposition for tactical advantage or safety.

Understanding the consistency of the firing position versus the more dynamic elements like direction, elevation, and rate of fire is crucial for effective machine gun employment in combat scenarios.
