This mission is identical, mission tasks and objectives, to the original version of Pitch Dark. The Total Stealth set of rules sounds just like the name; you need to make sure you are not seen at all (red warning). If this happens, then it is automatically a game over, so you have to go back to the previous checkpoint. As with the other rulesets, Chicken Hat and Reflex Mode are disabled.
As with the other repeat missions that involve total stealth, you will want to be extremely careful and take things slow, unless you're going for the S Rank. C4 is definitely the best option for the tank, as it allows you to detonate it from far away. If needed, Quiet can be a great distraction for this mission, as she can take out some enemies, while you go about your own business of finishing the main objectives.
