A unit citation is a formal, honorary mention by high authority of a military unit's specific and outstanding performance, notably in battle.
Similar mentions can also be made for individual soldiers.
Alternatively or concurrently, the unit can be awarded an honorary title, a mention on the flag or a decoration.
In France, since 1916, the fourragère (an ornamental colored cord) is worn on the uniform by the members of a unit which had received several citations. This tradition has since spread to other countries.
