Award classes
The Order of the Union of Burma is awarded in two divisions (military and civil) and each of these is split into five classes:
အဂ္ဂမဟာသရေစည်သူ Agga Maha Thray Sithu - Grand Commander
သတိုးမဟာသရေစည်သူ Thado Maha Thray Sithu - Grand Officer
The first class consists of a gold braided salwe worn across the breast with the badge of the order suspended. It is decorated with a large gold and enamelled breast star surrounded by five small stars.
2nd class honors have a single breast star that is smaller than the first class version.
3rd class honors have a badge, worn from a ribbon around the neck.
