The out by the end of March thing is a cash saving ruse by the MoD that works along the lines of anyone who has signed off and who has a date for leaving the service up until the end of Sep 04 can opt to leave early, provided that they have cleared (i.e. taken any terminal leave, resettlement entitlements, etc) by that date. Any gizzits not cashed in then are forefitted in exchange for being able to walk out the door on 31 March or before.
I would emphasis that this is voluntary and they do not have to take up the 'offer' but clearly some will particularly if they can't wait to leave or have already got a job lined up that they can start early. Of the 6 soldiers we offered this to, 3 have taken the option, one is staying with his original dates and the 2 others have signed back on!
With regard to the AFPRB announcement, this was released today (Wed) and becomes public tomorrow (Thu) at 1000hrs Z.
