Final answer:
Personnel or service record documents must cover all naval service day-for-day, tracking promotions, transfers, and casualties, with the Iraq War leading to increased mobilization and changes in annual drill requirements.
Step-by-step explanation:
The reports that must cover day-for-day all naval service on active duty or in drilling reserve programs, with the exception of initial entry training and certain limited circumstances, are likely to be personnel or service record documents. These records are essential for tracking a service member’s career, including promotions, reductions, transfers, and casualties, with the authoritative source cited in each case. As indicated by historical data and adjustments in drill requirements, the nature of reserve service has changed over time, necessitating accurate and detailed record-keeping.
For example, following the Iraq War, there was a significant increase in the mobilization of National Guard and other Reserve components, with nearly 28 percent of total US forces in Iraq and Afghanistan at the end of 2007 consisting of these personnel. In 2012, the Army's top general announced the intention to increase the annual drill requirement, reflecting the evolving role and responsibilities of servicemen and women, which reinforces the need for meticulous service record documentation.
