Final answer:
The armorer's report time can vary depending on the historical or contemporary military context. In ancient times, they had duties related to armor and weapon maintenance based on military needs. In modern times, such as in the US National Guard, the reporting schedule has become more demanding post-Iraq War with longer drill requirements.
Step-by-step explanation:
When asking about when the armorer reports for duty, it's important to consider that this role can vary greatly depending on the context and period being referred to. In historical contexts, such as Roman times, an armorer likely had a specific set of duties related to the maintenance and crafting of armor and weapons for soldiers. They would report for duty according to the military schedules and needs of the time, which could involve daily work or during specific periods of preparation for campaigns or battles. In more modern contexts, such as in the case of the National Guard and other Reserve components of the US forces, armorers would report for duty based on the military requirements. Post-Iraq War developments saw a shift in the typical 'One weekend a month, two weeks a year' slogan, where personnel might be mobilized for longer periods, as suggested by the Army's top general's intention in 2012 to increase the annual drill requirement. So the reporting times for a modern armorer could range from regular daily duties to extended periods during drills or mobilization for active deployment.
