The preferred age is 18, however men younger than that died in the Vietnam War.
they were to go to a type of school where they learned reading, combat and survival skills.
Athenian boys typically joined the military at the age of 18. They underwent a period of training known as the "ephebe," which lasted for about two years. This training included physical fitness, combat skills, and civic education, preparing them for their roles as citizen-soldiers in defense of the city-state. After completing their training, they were expected to serve in the military as needed.
In Sparta, boys entered military training at the age of 7, not 14. They began their rigorous education and training through the agoge system, which emphasized physical fitness, discipline, and combat skills. By the age of 14, they were already deeply involved in this training, honing their abilities to become effective soldiers. This early initiation into military life was central to Spartan culture and society.

The military doesn't have an age of consent.
In 420 BC, the age at which young men typically went to war varied by city-state, but in ancient Greece, it was common for males to join the military around the age of 18. For instance, in Athens, young men underwent military training as part of their education and were expected to serve in the army when needed. Some city-states, like Sparta, had a more rigorous and earlier military training system, with boys beginning their training at age 7. Thus, by their late teens, they were considered ready for combat.
Compulsory military service was abolished in Portugal on November 19, 2004. The minimum age is 18 years old for voluntary service. Women have been assigned to naval ships since 1993. But they aren't allowed to serve in certain combatant specialties.
Depends which military.
There is no compulsory military service in New Zealand. I'd expect that any person who was over age 18 and was of good character and education, would be welcome.
There are no special circumstances that allow military personnel to engage in sexual activities with underage persons. The laws that prevail are those established by the jurisdiction in which the military person or minor resides. In the case of a minor joining the military, (17 years of age) again, the laws that prevail are those of the state in which the minor resides at the time of the contact.
