Which cartridge type is used by the M4/M16 family?

Explanation:
The key idea is recognizing what cartridge the M4 and M16 family were designed to fire. These rifles are built around a lightweight, high-velocity round that lets soldiers carry more ammunition with manageable recoil and effective performance at typical combat ranges. That cartridge is the 5.56 x 45 mm NATO. It was standardized for NATO in the 1980s to replace heavier rounds while keeping reliable ballistics for standard-issue rifles. Other options represent different weapon families: 7.62 x 39 mm is associated with AK-47 variants, 7.62 x 51 mm with older NATO battle rifles like the M14, and .50 BMG with heavy machine guns and anti-material rifles.
