Final answer:
Duty rosters historically assigned men to various activities based on the era and military needs, ranging from intense physical demands in ancient armies to varied roles including combat and support in modern times.
Step-by-step explanation:
Duty rosters in different historical contexts and militaries show that men were assigned to various activities, depending on their era, location, and the specific needs of their military unit. For example, during ancient times, like in Roman society, service in the army was incredibly rigorous with soldiers expected to march long distances and undergo severe discipline for any dereliction of duty. By contrast, in modern history, during World War II, men's assignments varied widely from combat roles to support functions, such as driving ambulances or providing labor services when needed.
In the United States during World War I, nearly 4 million soldiers, mostly draftees, had to adapt to the strict military regulations, which quarantined men to control behavior, upholding views that the war was a moral crusade. However, gender roles in wartime also impacted assignments, with women gradually taking over roles such as ambulance drivers as more men were required at the front. Overall, duty rosters and military assignments were used to manage both the practical requirements of war and the behavior and morality of servicemen and women.
