Which phrase is associated with the M-16A4's service ethos?

• A. One shot, one kill
• B. Shoot twice quickly
• C. More firepower, less accuracy
• D. Aim and fire rapidly

Answer: (A)

The idea being tested is the emphasis on precise, effective fire. The M-16A4 is valued for accurate, controlled shots, especially in combat where first-round hit probability matters. The phrase “One shot, one kill” embodies that mindset: it communicates the goal of delivering a single, well-aimed shot that stops the target, rather than wasting ammo with rapid or careless fire. This aligns with training and doctrine that prize precision, discipline, and efficiency in engagement.

The other options push ideas that run counter to that approach—shooting twice quickly, equating more firepower with less accuracy, or aiming and firing rapidly—all of which imply sacrificing accuracy or wasteful use of rounds, which is not the ethos emphasized for the M-16A4.
