The Army adopted the Trainfire model around 1955. The most recent version revamped the program in the late 1970s and served as the primary approach until the new Training Circulars re-wrote doctrine starting in 2016.

Until the new TCs and qualifications for them, all changes to Army small arms standards have reduced the challenge and needed skill. Consider this video where Soldiers conducting routine qualification during Basic are advancing downrange with loaded rifles and expected to take up positions on timed pop-up targets. FM 23-8, which was doctrine when this film was made, included a four table qualification that included shooting while advancing, offhand, and other unsupported shooting. Also note the regular use of peer coaching.
