The following is based on Fallout Tactics and some details might contradict canon.
Training missions are the set of four Brotherhood of Steel training situations, where the initiates prepare for real combat in the Training Centers. The situations are Basic, Ambush, Stealth and Sniper.
These training scenarios are organized and supervised by Paladin Ziskele and the leader of the Training Centers (where the basic training takes place), Paladin Rychek who can be seen in the introduction and many renders of Fallout Tactics.
Notes[]
The Ambush, Stealth and Sniper missions actually take place in map parts of Dirt Haven and Devil's Graveyard.
The basic training takes place in an new bunker not seen during the game called Training Centers, where unique objects and characters could be seen - dummies, created for shooting practice.
The video guides on how to solve a training mission's objective are shown before each of these missions.
