What is the MK45's maximum firing rate?

• A. 20 rounds per minute
• B. 10 rounds per minute
• C. 30 rounds per minute
• D. 15 rounds per minute

Answer: (A)

The concept being tested is the highest rate at which a weapon can cycle and feed rounds, measured in rounds per minute. For the Mk 45, the design and mechanism limit the firing cycle and ammunition handling to about twenty rounds per minute at maximum. This is the ceiling under safe, optimal conditions; pushing faster would tax the loading and feed system and risk jams or unsafe operation. The other options are simply slower or faster than what the gun can reliably achieve: ten or fifteen rounds per minute are below the maximum, while thirty rounds per minute would exceed the weapon’s mechanical capabilities.
