Nightingale Squad

Nightingale Squad, also known by their fellow clones as the Nightingales was an elite squad consisting of four Clone troopers and a Jedi General, who were assigned with two major tasks: assisting the Jedi in any roles the Jedi Order needed filled and conducting special, covert operations behind enemy lines during the Clone Wars. Thought to be the best soldiers in the Republic military, the Squad was adored by the Republic and feared by the CIS.

Members
Nightingale Squad consisted of five members: While this was the main squad, the group was also assisted by others, such as Master Liko Eil, a Zabrak Jedi archivist who often gave them intel involving Jedi artifacts, and Officer Fen, a Clone officer who was often the one to guide the mission through covert missions via radio.
 * Jedi Master Jeden Vesal, leader of the group and a General during the Clone Wars. It was from Jeden's personal attack cruiser the Phantom that the Squad operated from, and it was under his leadership that the group won many battles and conducted multiple missions.
 * Commander Phoenix (CC-1450), the commanding Clone of the group and the best friend of Jeden. The best sniper in the Republic military, Phoenix was known for his sense of humour and optimism, though he was also an excellent soldier and leader.
 * Wraith (CC-1451), a lieutenant and a stealth expert. Wraith owned a stealth field generator, allowing him the ability to cloak himself at any time. Wraith saved the lives of the squad countless times with this ability, though this grew a cockyness and arrogance that hasn't gone away.
 * Twenty (CC-1452), a lieutenant and Wraith's best friend. Twenty was named after he took down twenty fellow Clones from a rival division in a Kamino mess hall with his bare hands. Both incredibly strong and quite nervous, Twenty was a gentle giant, not liking violence despite his great strength. He was also the supply carrier of the group, and while Jeden was the best healer, Twenty also carried medkits and knew basic first-aid.
 * Sting (CC-1453), also a lieutenant and a master of melee combat. Sting wielded two vibroblades, which were hidden in sockets on his wrists. Sting was very seclusive, and was very protective of his privacy, though he proved to be a vital team member, being an expert with acrobatics and two very dangerous vibroblades.

History
The group originally comprised of the four Clones, who were trained together and seperate from other Clones. Designed to be the most effective members of Republic special forces, the group had their first taste of combat on Geonosis, where they encountered Jeden Vesal, a Jedi Knight. However, only Phoenix spoke with Jeden, while the other three didn't speak to him until he had become a Jedi Master and became the leader of the squad from the Phantom, a Venator-class cruiser.

Conducting multiple operations for the first two years of the war, the group had become famous among both sides of the War as a dangerous fighting force. This wasn't just for the Clones, either, as Jeden had been the first Jedi to fight General Grevious (Grevious had imprisoned Liko Eil on Mygeeto, and Nightingale Squad was chosen to rescue the Jedi). Jeden was able to slice off two of Grevious' arms, forcing him to flee.

By 20 BBY, Nightingale Squad was in the space surrounding the Core Worlds. Noticing a smugglers frigate, the Squad boarded it and found millons of credits worth of stolen goods. However, one of the smugglers, a Twilek thief named Nara Sa-el, stole an ancient Sith crystal and set the frigate to blow. The Squad escaped, but now the Jedi Council wanted to find the crystal, so the Squad and the Phantom pursued.

Eventually coming to Ord Mantell, the Squad learnt from Jeden what Nara was carrying and why it was so important, as the crystal was full of dark side energy which, if released, could cause an explosion the size of a moon. With this knowledge, Nightingale Squad went with around fourty Clones to Ord Mantell, making their ground HQ as Fort Garnik, an abandoned Republic fort once used in the era of Darth Revan. Nara was hiding in a nearby volcano, which had once been a Sith base, so the Squad travelled to the volcano during the night, learning that Nara had taken children from a nearby farming village as hostages.
