For service in so-called "Peace Keeping" or "Peace-Making" missions abroad, a mission medal is awarded after some time.

For UN medals it is usually 90 days of service and for NATO medals it is 30 days of service.

Medals that are mounted in straight bands must normally have this changed to a so-called "Krydsbånd", which is only used in Denmark.

However, medals that are provided with a "Bar" - the small metal badge with text on the ribbon, are exempt from this rule.

Just for the NATO medal, there is an exception for the ribbon in the Danish Army UBH - it can be worn both as a cross ribbon and as a normal straight ribbon.

However, I think that the most "right" way is that it is worn with straight straps as shown here, - at the same time it looks somewhat amateurish when a metal "buckle" is tried to be mounted on a cross ribbon.
