Even if a person is deemed fit, or partially fit for service, he may avoid having to serve if he draws a high enough number randomly. Persons who are deemed partly fit for service will however be placed lower than those who are deemed fit for service, and therefore have a very low chance of being drafted. Men deemed fit can be called upon for service until their 50th birthday in case of national crisis, regardless of whether normal conscription has been served. This right is very rarely exercised by Danish authorities.
