Phase 3 starts no earlier than which day?

• A. Day 48
• B. Day 60
• C. Day 40
• D. Day 50

Answer: (A)

Phase progression in basic training is timed so Phase 3 cannot begin until enough days have passed to complete the prior phases and their required activities. The calendar sets the earliest start of Phase 3 at day 48, ensuring there’s sufficient time for the earlier phases’ drills, exams, and field activities, plus the Phase 3 events that lead to graduation. So day 48 is the earliest possible start. Starting earlier isn’t allowed by the schedule, and while later starts like day 50 or day 60 can occur on different rotations, the question asks for the earliest, which is day 48. Day 40 would be before the minimum.
