What is a characteristic of automatic or burst fire?

The characteristic of automatic or burst fire being a continuous discharge of ammunition is accurate because this type of fire mode allows the firearm to fire multiple rounds with a single pull of the trigger. This means that, unlike semi-automatic fire, where each shot requires a separate trigger pull, automatic fire can produce a rapid succession of rounds, effectively saturating a target area or providing overwhelming firepower.

In a burst fire mode, the weapon is programmed to fire a set number of rounds (commonly three) before requiring a release and pull of the trigger to continue firing. This can be particularly advantageous in combat situations where maintaining fire on a target without interruption can provide a strategic advantage.

The other options do not accurately describe the nature of automatic or burst fire. A single shot with a pause does not align with the definition of either automatic or burst fire, as they both involve multiple rounds being discharged in quick succession. Stating that automatic fire is only utilized in close combat is misleading, as it can be effective in various combat ranges and situations. Lastly, the requirement for two operators does not pertain to automatic or burst fire specifically, as these firing modes are typically managed by a single operator.
