It is NOT a tutorial but an in-game review system where the player can ask for assistance on improving specific elements of their gameplay once they have completed the mission. not KIA

Overview
Once a mission has been completed, user has option to review mission with the purpose of improving (kills, accuracy, stealth, assualt etc)
1. Based on the class role (panther, sniper etc) a mentor walks them through the best weapons, attachments, perks used to accomplish this mission to to improve whatever they listed above
2. mentor walks them through the most popular path to tackle this base to improve , showing points where they might have waited and observed, sniped someone etc
3. based on player abilities, offer suggestions on modifying game settings like sensitivity, danger sense, crosshairs ,
4. point out gneric mistakes, you were spotted because you didnt scout and highlight the person looking at hem or you didnt prioritize targets or your aim wasnt quick enough

The mentor would walk them through inside gameplay and offer directions, stop here, scout area, hide behind cover or prioritizing targets to improve aiming, kills etc.
at the end of the mission review, chance to replay mission to test out suggestions
