The main idea is how bullet weight and design drive general purpose and long-range capability. M193 uses a 55-grain full-metal-jacket projectile, which is a lighter, high-velocity standard ball round optimized for flat trajectory and reliable performance at typical engagement distances. M855 uses a heavier 62-grain bullet that includes a steel penetrator in the tip, giving better penetration and improved performance at longer ranges. The green-tip designation of M855 signals this penetrator design aimed at increased barrier penetration and extended range, not a lighter, simpler round. So, the correct statement matches the real differences: M193 is 55-grain FMJ, while M855 is 62-grain with a penetrator designed for longer-range/greater penetration. The other options mix up weights or characterize the rounds incorrectly, and none accurately reflect the true distinction.
