Which pairing correctly matches the MK19 sustained rate with its burst pattern?

• A. 40 rpm, 3-5 rd burst, 4-5 sec pause
• B. 60 rpm, 3-5 end burst, 2-3 sec pause
• C. 450-550 rpm, continuous burst
• D. 325-375 rpm, continuous burst

Answer: (A)

Firing at a sustained rate focuses on heat management by using short bursts with pauses. For the MK19, the sustained rate is about 40 rounds per minute, with bursts of 3–5 rounds and a 4–5 second pause between bursts. This cadence keeps the weapon from overheating while still delivering effective fire. Other patterns describe much higher firing rates or continuous bursts, which would quickly overheat the launcher and compromise reliability. So the pairing that matches the sustained firing pattern is 40 rpm, 3–5 rounds per burst, with a 4–5 second pause between bursts.
