Then-Lt. Col. George C. Marshall Jr. revolutionized the curriculum at the Infantry School at Fort Benning, Georgia:
By the time Marshall departed Benning, the number of hours devoted to tactics instruction in the Company Officer Course had nearly doubled from 221 to 400. For the Advanced Course, it totaled almost 800 hours.
[...]
He championed the concept of the holding attack as the standard operation that commanders at any level could adapt to a wide variety of situations. While one element fixed the attention of the enemy with fire or a frontal attack, another would maneuver against a flank, and the third would remain in reserve to exploit whatever opportunity arose.

To ensure that students could actually implement these concepts, Marshall moved most of the tactics course out of the classroom and into the field.
