Usually, the more elite a unit is, the more specialists it has. Every military unit has different specialists, people with special training and special jobs. Here is a list of some of the duties a unit may have. It is by no means complete but it might help you figure out exactly what that one character is doing in a team besides carrying a rifle. Riflemen come a dime a dozen and a special operations group is not going to waste time with deploying a rifleman. A special Operations group will frequently train specialists as riflemen or riflemen as specials because riflemen are usually easier to train. For instance, on a Special Forces team everyone has one or more specialties. A bridge crew is full of different specialists, each one with a highly technical job. As combat becomes more complex so will infantry units.
