U won't get a recourse - the 24 months is not sufficient to do that efficiently.
They will post you out...as and when CMPB decides. Its not for the unit to decide.
Sometimes can take weeks/months - depending on the army's needs. They can't post you to places that are already filled.
Just be patient and wait....
Watch your back injury. It doesn't become magically normal after just one month. Don't push it too hard.
