Your are right, a lot of people are not aware of what they signed up to when they PVR'd especially those who haven't completed a pensionable term.
The good news is that the nice Mr Bliar has already stated that any reservist failing to respond to a call out will NOT be jailed.
In my particular case I have absolutely nothing to worry about!
I also left after 28 years with no reserve commitment.
