Ka'rta Tor

"Ka'rta Tor", meaning "One Heart of Justice", was an ancient Mandalorian war chant. During his training of the Clone troopers of the Republic, Jango Fett revised a number of chants, including "Gra'tua Cuun", replacing traditional Mandalorian keywords with more appropriate Republic ones. In this instance, it is presumable that he replaced "the Mandalorians'" with "The Republic's".

The chant was sung by the Clone troopers with the accompaniment of drums and horns.

Ancient Mandalorian
Kandosii sa kyr'am ast, Troan teroch jetiise a'den, Duraan vi at ara'nov. Vode an, ka'rta Tor. Kote.

Basic Translation
As ruthless as Death itself, The pitiless face of The Republic's wrath, Let us look down on all who before us. Brothers all, one heart of justice. Glory.
