IN RESEARCH ON JUNIOR NCO LEADERSHIP PREPARATION FOR ADVANCED BASIC ARMY TRAINEES, A LARGE SCALE EXPERIMENT CONTRASTED THREE LEADERSHIP TRAINING TREATMENTS AND TWO CONTROL TREATMENTS. THESE WERE SYSTEMATICALLY APPLIED TO EACH OF FIVE COMPANIES IN A SINGLE BATTLE GROUP AT AN ARMY TRAINING CENTER IN 1961. THE STUDY INVOLVED MORE THAN 400 TRAINEE LEADERS, 4,000 FOLLOWERS, AND 145 CADRE ORGANIZED IN MORE THAN 20 CYCLES AND 80 PLATOONS. INTENSIVE ANALYSIS OF 21 SELECTED CRITERIA INDICATED THAT, AMONG OTHER FINDINGS, TRAINED LEADERS RECEIVED HIGHER RATINGS, THEY AND THEIR FOLLOWERS PERFORMED BETTER ON MILITARY PROFICIENCY TESTS, THEIR SQUADS SHOWED HIGHER ESPRIT, AND THEY PREPARED, BRIEFED, AND CONTROLLED THEIR SQUADS BETTER ON A TACTICAL FIELD EXERCISE. THEY ALSO HELD MORE FAVORABLE ATTITUDES TOWARD THE ARMY, ALTHOUGH THEIR FOLLOWERS TENDED TO BE LESS FAVORABLE TOWARD THE ARMY AND TOWARD TRAINEE LEADERS. AMONG THE LEADER TRAINING TREATMENTS, BOTH CRITERION MEASURES AND ADMINISTRATIVE CONSIDERATIONS INDICATED THAT A LEADER PREPARATION COURSE (LPC) TRAINING SYSTEM WAS PREFERRED OVER LEADERSHIP TRAINING INTEGRATED WITH ADVANCED INDIVIDUAL TRAINING.
