Sith Officer uniforms may vary in color from light to dark gray, dark gray-green, or black. Generally, a strap connected from a left shoulder epaulet running cross diagonal to a utility belt. Boots and caps usually matched the color scheme of the torso, but may also vary as well. Sometimes, they also wore on their left breast a plate with various colored lines on it.
Many, if not all of these officers served in the Mandalorian Wars under Revan and Malak. As many Sith Officers were the commanders of Republic ships such as the Leviathan and the Ravager during the Mandalorian Wars, they took these ships with them when they turned their backs on the Republic. Many of these officers, especially Admiral Saul Karath who destroyed an entire planet (Telos IV), changed so quickly into ruthless monsters suggesting that the dark side of the Force affected them as it had affected Revan and Malak.
