Military discipline requires soldiers to follow certain rules when working together militarily. These rules help soldiers to perform their duties correctly and safely, and ensure that the unit moves effectively. Therefore, every situation of the soldiers has been determined by strict rules in advance, and this order is applied in a strict way. The clothing of soldiers are also subject to these rules. According to the rank of each soldier, his uniform, epaulette and even the button of his uniform are subject to certain rules. The uniform button lot exhibited in our museum are buttons that show that soldiers who served in different armies during World War I are affiliated to the artillery unit. On the buttons, there are coats of arms indicating the army and the union to which they are attached.
