The article isn't completely true. The 5.56 was selected because it's significantly lighter and smaller (soldier can carry more ammunition), produces less recoil (soldier can be less trained but still effective, especially when in full-auto mode... which pertains to CQB), and is effective within the average engagement range (<600m). Most 5.56 weapons also have higher rates of fire when compared to their 7.62 brethren, which also plays a significant role in CQB effectiveness. Regarding "stopping power"... a round from either will incapacitate most humans, and the latest generations of 5.56 can penetrate light to medium armors very effectively. Since NATO adheres to the Geneva Conventions, firing upon medical troops is forbidden, as is deliberately wounding but not killing enemy combatants, making the author's claim even more dubious.
