tl;dr summary, you'll probably get to stay and you'll probably get to fly a more normal amount, and you'll probably look back on it as being worth it
You're young. Have patience. I wasn't at that OG/CC call, but the previous WOM I'd heard was that brand new B-Course grads are *not* being sent off to do other things. The temporary crew force redux is hitting the middle tier of experience (broadly speaking), spread out across year groups. The whole point of drawing down manning is to ensure that those who stay can fly, gain experience, and upgrade on a more normal timeline (and not get bottlenecked as has happened a lot recently) given reduced sortie availability... While those that go elsewhere use their experience to add value elsewhere in the CAF, and learn things that will add value to the B-1 when they return.
The circumstances suck, but the community has weathered worse and bounced back to bigger and better things... e.g. the early 1990s trying to figure out if it still had a mission after the Cold War, and the early 2000s when the fleet and the crew force was permanently reduced by 1/3rd. You can look at this as "I missed the 18 fat years, and arrived just in time for the lean ones," or you can look at it as an opportunity to be on the ground floor of creating something great. I spent 8 years on the Octobomber, arriving a few years after the "Nukes Across America" incident when it was nuclear exercise after nuclear exercise occasionally punctuated by Guam. People that were short term thinkers looked for the first opportunity they could get to punch to something else (ALFA tours, green door assignments, rando non-flying staff gigs, etc.), and missed going to combat. Those of us who stuck around and tried to make our corner of the AF better eventually led the way when we went back to CENTCOM. Likewise, I suspect the B-1's finest hour is still ahead of us.
