305/305 Physical, 450/450 Mental, 349/350 Tactical
Both of these seems to have exactly the same chance of succeeding.
If you complete all three requirements it becomes a 100% chance of success. If you complete 2/3 of the requirements he says "Your squad seems to be equal to the task." This seems to be something like 50-75%. So keep in mind, that even though your three stats may be at 304/305, 449/450, 349/350, you still haven't met any of the requirements and he'll say your chance of succeeding are practically zero.
