For each campaign mission, there will be a set of challenges you need to complete in order to unlock the "Master Tactician" achievement. These challenges can be completed on any difficulty apart from the ones that specify to complete them on Elite or Veteran. Once the challenges are complete, don't worry about dieing or failing an objective straight afterwards or later on in a mission, as the challenges stay completed.
I have a set of videos I would like to share with you all, and in which, I do fail, die and sometimes intentionally restart checkpoints or the whole mission to attempt a challenge at a different difficulty setting or with a different weapon. In saying that, the videos are not a mess and don't showcase five or six retrys of the same challenge.
Each mission also requires you to achieve a Ghost Score of 60% (very easy) and complete each mission on Elite. Here's a rundown of the challenges for each mission:
