pir=Pass In Review or graduation after 8 weeks of boot camp
You have plenty of time to learn these things. You will be an expert by the time his PIR gets here. Do join the groups I have previously recommended--at least DEP-Leavin for bootcamp in May and Boot Camp Moms (and loved ones). Be sure to check out the discussion, Things to Do in the Last Month Before Your Future Sailor Leaves for the RTC.
