The life of the soldiers of the Roman Republic?

In the early Republic, any Roman between the ages of 17 and 46 who owned property could be drafted into the army. This service was considered compulsory for the citizens of Rome.
During their service, the soldiers made 16-17 military campaigns, some remained in the army forever. By 100 BC e. most of the warriors were already professionals. Three times a month the army made marches 30-40 kilometers long. The warriors walked at a fast pace: at a speed of 6.5 and even 8 kilometers per hour. Legionaries learned to build and assemble a camp.
When entering the army, the recruit took an oath of allegiance. Before it was a promise to fulfill the orders of their commanders, then – an oath of loyalty to the emperor.
The guilty soldiers were subjected to corporal punishment. A Legion that showed disobedience was reduced in food ration; if there were riots, then decimation was carried out – execution by lot of every tenth soldier.
Under Caesar, the legionnaires received a salary of 225 denarii a year. Emperor Domitian upgraded it to 300 denarii. The soldiers had to buy food for their own money, which took a third of their salary. The food was simple: cheese, beans, bread or cakes made from wheat or barley flour. The soldiers’ drink was water or posca – a cheap sort of wine.
The military training was very difficult. Every day the soldiers of the legion trained in swimming, running, jumping, dart throwing and fencing. In addition to training in military affairs, the soldiers studied the craft of a land surveyor, builder, bricklayer, and also learned how to build roads, canals and various buildings.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
