I appreciate everyone's efforts to expand my knowledge.
I found the official Djibouti online legal database, which is in French - I speak it fluently but have to work at reading it! - and its search facility is not very good. But as Emmanuel says, what has been legislated is not always quite what happens once the award actually gets made and given out.
As an example, there was a discussion recently on the OMSA site about a growing tendency for senior officers awarding medals which are worn on the breast according to regulation suspended on any old length of neck ribbon (often not even the right ribbon). We concluded that they either didn't like fiddling around pinning medals on chests or just thought that hanging something round the neck, sports medal style, made for a better photo opportunity!!! But to those who did not know that the medal should be worn on the chest, the photos from the award ceremony would give incorrect information, especially if you didn't have access to a picture of the recipient wearing the award correctly on his uniform under normal circumstances.
