Question is - how many incidents like the one you describe, have happened?
As to the controller issuing instructions to the wrong a/c - then he's an arse! Even a chimp can see which way the talkdown a/c is going.
If the powers that be are worried about the data block going with another a/c, then why not terminate service at that point and use the good old "radar contact lost - are you visual with the airfield?" procedure that worked perfectly well with the old kit?
It really deosn't take the brains of a genius to solve the problem - instead of which, the whole military ATC system has spent the last day working out a series of differing and riduculous procedures to make the new STC rules work.
Milatary ATC has shot itself in the foot again, and made itself look a right bunch of Tw&*#s to the flying fraternity.

At my airfield we won't accept you or foreign a/c for PARs - you will have to do with SRAs and hope the cloudbase is not too low for you to get in
