In some countries, service ribbons are mounted on a "pin backing", which can be pushed through the fabric of a uniform and secured, with fasteners, on the inside edge.
After the Second World War, it was common for all ribbons to be mounted on a single metal bar and worn in a manner similar to a brooch.
Some countries (such as Cuba) maintain a standard practice of wearing full service ribbons on combat utility clothing.
The reasoning for such regulations is to prevent these displays from enabling opposing forces to easily identify persons of higher rank and therefore aid them in choosing targets which will have a larger impact on the battlefield.
Medals and ribbons not specifically mentioned in the "Order of wear" are also generally worn on the right side of the chest.
In the United States, for example, those with the highest status—typically awarded for heroism or distinguished service—are placed at the top of the display, while foreign decorations (when allowed) are last in the bottom rows.
