That has become part of being a member of the armed forces in the 20th century.
Soldiers are really just a number.
I work in a factory, and in a production environment the employees are treated a lot like a soldier. Also very little sympathy or mercy is excersized in the plant, they don't expect anyone to be sick and miss time, and making mistakes is even further from being understood. They didn't bother to give a moment of silence, or be careful with the body out of respect. They just chalked up another loss, washed him out, and put his replacement in the turret. They do this the same way in the plant.
