The training varied from unit to unit. Most Regiments contained two battalions. The first battalion was ready for use overseas. The second battalion was used as a training battalion and also used to replace casualties. When the first battalion was overseas the second would train new recruits and then ship out those who were trained to the first battalion as was needed The most basic training lasted about four weeks during which time the recruit was taught how to shoot, drill and the Queens Regulations. This time period was expanded for more elite units and cavalry. In times of great need men were often trained for a week and then send to the front to be trained by the men in the first battalion under fire.
