Super tactical droid/Legends

The super tactical droid was an upgraded model of the T-series tactical droid, used by the Confederacy of Independent Systems as a battle droid commander during the Clone Wars. Super tactical droids often served as generals in the Separatist Droid Army.

Characteristics
Super tactical droids were created for the Separatist Alliance in the Clone Wars to address shortcomings in the T-series tactical droid. They stood 1.94 meters tall.

History
Around 20 BBY, the super tactical droid General Kalani was sent to aid King Sanjay Rash of Onderon in quelling a rebel uprising on his world. The droid seemed to dislike Human tactics, seeing itself as superior to its flesh-and-blood counterparts. It focused only on the most likely attacks and refused to consider alternatives. It was overly suspicious of any display of pity for the rebellion, and pursued cutthroat tactics that were often questioned and disregarded by its human counterpart, General Tandin. Following a rebel victory, Count Dooku ordered General Kalani to leave the planet, so Kalani executed King Rash and retreated his forces to Agamar.

Not too long after, another droid named Aut-O was commander of a small fleet of light destroyers and a dreadnought. He was decapitated by R2-D2 when the droid fell on his head. Another super tactical droid was seen inside the Renown that D-Squad took refuge in after escaping Abafar.

Behind the scenes
Super tactical droids first appeared in Star Wars: The Clone Wars Season Five.
