Hopefully, they're still doing that and, more hopefully, the students hear and will heed the message.
Went to look for this to compliment what to you posted:

Battle Drill.--The teaching of battle drill undoubtedly proved to be of the greatest value in instilling dash and determination into troops and junior leaders. The best results have been obtained from battle drills on a platoon level, but training in the drills up to company level proved useful.
It is important, however, that junior leaders should not regard battle drill as a universal panacea to be applied in toto in every situation. Battle drill training aims at teaching the basic "strokes," and thus represents only the first rung in the ladder. The drills must be intelligently applied in accordance with the nature of the ground and the particular tactical situation. There were many occasions when unnecessary casualties resulted from poor leadership because junior leaders blindly followed a set drill and failed to apply it with common sense. - Notes From Theatres of War, No. 16, North Africa November 1942-May 1943; The War Office, October, 1943
