Final answer:
While the timing between conducting HT/WT and the APFT is generally up to a commander's discretion, guidelines may vary, and there is no explicit standard interval. Changes in military training reflect the increased commitments beyond the "One weekend a month, two weeks a year" norm, accounting for operational needs.
Step-by-step explanation:
The question addresses the period commanders should wait between conducting Height/Weight (HT/WT) measurements and the Army Physical Fitness Test (APFT) for soldiers. While the specific time interval may vary depending on the branch of the military and current regulations, it is generally not explicit within training guidelines. The decision on when to conduct the APFT after HT/WT essentially falls under the commander's discretion, considering the soldiers' readiness and any official guidance at the time.
It's worth noting that military training and operational commitments have intensified over the years. From the once-standard "One weekend a month, two weeks a year" commitment, changes have been made due to operational demands, such as those during the Iraq War, where significant numbers of the National Guard and other Reserve components were mobilized. In 2012, a proposal was made to increase the annual drill requirement to up to seven weeks per year, reflecting the evolving nature of military training and readiness demands.
