The older soldiers (grown ups) come and take the kids, all different ages to the battle feild anytime they need more soilders. They use these kids as sheilds. When they are fighting they have the kids in front of them so whoever is fighting them has to decide if they want to shoot at the little inasent children. They also are used to check for bombing sites. They go into the ditches and see if anything blows up. They are also used because they are too young to understand what they are doing.
