I think I can help some, but I'll preface it with I had a very odd run at things and did a whole lot of it out of whack with the normal progression and timeline.
That said, you're right on the Reserves pipeline all being on continuous orders; although it's not ONE set of orders that spells the whole pipeline out, but just a continuous path through all of the training with orders cut back to back so you're never "off" orders and not in training/not getting paid. For the Reserves, all pilots (no matter the airframe) are put into the 340th FTG, so there's one POC handling the entire training pipeline. So, technically, we're not owned by our home units until (at least) after UPT. No drill weekends while waiting to leave and no real interaction with your home units, besides check-ins. The 340th handles all pay, travel/PCS, orders, leave, questions, etc.; nothing is handled by your home unit.
The Guard has each individual unit handling things, which means each unit is fighting for limited training slots in each piece of training (OTS, SERE, IFT, UPT, etc.), which can sometimes lead to big breaks in the training. They also "own" you immediately, so you're attending drill weekends and all issues (pay, orders, travel, etc.) are handled directly by them. Any waivers have to go up the chain from unit, to state, to NGB, which can be disjointed, from what I've heard.
Pros and cons to both, but I've appreciated the Reserves single POC/continuous pipeline aspects and knew it would move things a little faster along, which was important with my advanced age.
Anyway, in the Reserves pipeline, you'll go to Inprocessing at Randolph about 2 weeks (can vary, but usually within a month) before your OTS start date. That will be a separate set of orders than OTS and you'll be back off orders after it. Starting with OTS, they'll do just about anything, scheduling-wise, they can to keep you on continuous orders (less than 30 days break in training/authorized delay). As of now, I can only verify this is through UPT, which will also include SERE and IFT (if you don't have a PPL already) and not further through FTU/unit seasoning, because that's my experience thus far. The orders are broken up, so it won't be one set that takes you through everything, but they write them to be back to back as you go through the pipeline so you won't have any breaks in pay/being on AD orders.
For instance, I have OTS orders that end after graduation, that follow the very next day with my PCS to my UPT base, break in training, SERE, break in training, and then start of UPT/T6s. I had initially seen orders taking me completely through UPT, but they got pulled back before full approval and they were cut down in number of days, but the timeline and dates are the same.
Speaking of which, I dunno if I've ever put a full timeline of my little journey up here, so here goes:
Dec 2017 - AFOQT
Mar 2018 - TBAS
May 2018 - MEPS
July 2018 - FC1
July 2018 - Interviewed with Reserves heavy squadron; told I was hired less than 36 hours after leaving. They hustled to get my age ETP/waiver signed and up the chain, as well as my packet together, for the next UPT/OTS board, which was beyond awesome and super helpful. I also annoyed anyone I could to help expedite things along. Plus, being old as hell (I was 36 then) helped, too. So, my paperwork likely moved quicker than normal due to that stuff, I think.
Sep 2018 - UPT/OTS board; picked up by board
Dec 2018 - Inpro with 340th FTG at Randolph
Jan 2019 - OTS
Mar 2019 - PCS to Vance
April 2019 - SERE
May 2019 - May 2020 UPT (I have orders only to T1 start, due to FY break/funding
FTU and Prog Tour dates TBD, but likely following a PCS back to my home base at the completion of UPT, before the TDY to the FTU.
YMMV at all of this, but that's the general Reserves system and timeline.
