Excellent article.
When we first arrived in Vietnam in 1967 we had trained on M-14s.
When the Army issued are new M-16s, in Country ( with all the buffer problems that came with it), there was a limit on the rifle to only three-round burst and no full auto.
Full wastes ammo, is less accurate, and makes the user feel safe when it actually often creates exposure and mag change fire gaps.
Excellent article.

The author speaks from the rifleman’s bible. Marines are always told it is never how many rounds you send down field, but how many reach their target. One shot, one kill is the most efficient use of the weapon.
I thought the 3 round burst mechanical function, in lieu of the full auto option, was introduced long after the Vietnam war ended. What am I missing? Did I misunderstand your post Key?
