Training droids were droids used for training and honing various skills, such as lightsaber combat or marksmanship. The hazards that training droids incurred widely varied. Some, such as the Marksman-H, delivered harmless shocks to the trainee; others, such as Darth Vader's dueling droids, could kill an ill-prepared trainee.
In a military context, if training droids were equipped with higher-power weapons, they could be employed on the battlefield. Moreover, training droids used for marksmen to practice quick-draw skills, reaction times and accuracy.
In Jedi training, the use of training droids developed the Shii-Cho combat form. Furthermore, the droids recorded the actions of two combatants in training and measured their vital constants. Other training droids were equipped with lightsabers instead of light blasters. Training droids were also used in Sith training, with Sith Lords such as Darth Maul and Darth Vader using them to hone their lightsaber skills.
