The U.S. Army is in the process of implementing the Army Distance Learning Program, which is intended to improve training effectiveness and efficiency by substituting distance learning (DL) for portions of its current resident instruction program. To determine the potential effectiveness of DL in delivering military training, 25% of the resident portion of the Armor Captains Career Course was converted to DL and the time allotted to that portion of the course sequence was reduced by 30%. The revised course consisted of a 16-day DL phase and a 94-day resident phase. With that course structure as a basis, four alternatives to the current practice that involved different combinations of permanent change of station (PCS) and temporary duty status (TDY) were explored. Depending on the mix of PCS and TDY status, the four options increased the time on home station from 32 to 43 days per officer and yielded a minimum estimated increase of 8-15 available duty days. The effect on trainees' well-being varied among the options. Three of the four options were slightly more expensive than the existing training system; however, DL conversion enhanced stability by keeping soldiers in their units longer.
