Description: The medal consists of a Leopold cross inside of a circle of laurels. In the center of the obverse is a disc with prince Carol's I profile (in 1872; king from 1881). Around it is inscribed the text: Carol I Domn al Romaniei. The 2nd class was silver, while the 1st class was golden. The ribbon was red and the margins were light blue.
The medal was issued initially to officers and NCOs who had a long military service record, but after the 1877-78 war broke out it was decided to also be awarded for exceptional deeds on the front. To differentiate between those who earned it for an extended service and those who won it on the battlefield, to the former category was added, between the medal and the ribbon, the numeral XII.
By WWII, the medal was no longer awarded for a long military service and was strictly reserved for battlefield deeds.
