I've just copied this from QR's, just for clarity
Thanks for the clarity.
The pertinent date being 01 Jan 1991 ( I was at the 12 year point in 91 )
A new thing ( that I must have missed / ignored / forgotten about ), probably something to do with being in a sandy place on said date
That being said - between 1991 and 2001 there was still people signing up on FTC's and I certainly cannot recall any soldiers coming in on Open Engagement.
Perhaps recruiting offices were still pushing FTC's
