b. displace a pilot junior to them in the same position in a different base, or

c. displace a pilot in any category who:

1) was in such category on the award date of the pilot who holds the VD, and

2) is junior to the pilot whose displacement they volunteered to take.
Either way, you’re right in that if you hang around in a long draw down you could get junior in category real quick. OTOH, reserve in an over-manned category can be massively great QOL.

Both VD and MD get paid moves.
If you need training, a VD is a seat lock, and MD is no seat lock.
