Here's some more information:

The Expected timeline will look like this
Day 0 -- Travel, Arrival and "I'm Here" scripted phone call
Day 1-14 -- ROM (Restriction of Movement/ Quarantine-- Lots of studying and waiting)
Day 15-21 Arrive Onboard RTC and begin P-days (P-days- Initial Processing Days) including 2 days of P-hold (Weekend)
Day 21-- Complete P days. (Initial PFT & Run)
Day 22-- Begin training and mail form letter out. Look for it to arrive around 1-2 weeks later)
All of this is assuming no exposure to COVID with additional ROM
Training typically occurs Monday - Friday but we have heard rumors that Saturday’s are now training days as well.
Normal PIR will be 10 Fridays after departure from Home but it can be less by 1 but it can be extended by ???? (lots!!) It just depends on how many times they get caught in the “Ring of Fire” but do not get COVID. IF they get COVID, Once they are recovered they will not be removed from training again even if they are in the “Ring of Fire”. (so there is that small silver lining if kids get sick)

Phone Calls Home other than for the "I'm here" Call are
"I'm In ROM" (Expect a 2 week Delay)
"I'm out of ROM Here is my new PIR date and Div" (Ask for the address just to be safe but it is a Business call and not for chatting.
"I Need more Information" Also a Business call and not for chatting. They often have an RDC right there. Be sure to tell them you love them and ask for their Ship & DIV number if you get this call. We can help you find the address

"Hi Mom!!" (aka Proof of Life) These are the BEST calls.  They are social calls that can be anywhere from 15 minutes to 60 minutes.  These calls are earned and usually will come anytime  after 5 weeks from departure. They can earn none, 1, 3 (Most common) or more! Answer all calls while your SR is in BC!!
and Finally "I'm a Sailor".  They do not know we call it that so don't be surprised if they don't say that when they call.  This is the final call before they are readied to leave for A School.  Not all Sailors choose to make this call so if you don't get one don't freak out! No News is GOOD News!!

There are also calls that you don't ever want that are to inform you of injury, illness or separation but I won't dwell on those.

Hi Splash23 and welcome,

we are glad that you are here. When you join the Boot Camp for Moms please come and introduce yourself. You will scroll all the way down the page until you get to a box called the comment wall. that is where we ask questions and talk to the other moms on here.

Sorry to hear that you missed that phone call it sounds like he needed more information. 

Did he just leave today? If so, please keep your phone on you at all times and that ringer on loud so you won't miss his first call. It usually comes late in the evening and the call is scripted letting you know that your loved one made it there.

Welcome again.
