I think this is a bad idea that is going to screw over members and commanders alike. If we were in a time of massive mobilization I could see using the broken to teach the people heading to the front but this is just a way to artificial keep numbers up. I could totally get behind 68000 deployable members and 32000 who are posting/deployment restricted for some reason but we all know that won't be the case.
We already remuster broken people into trades they can do within their MELs and we already retain people who, in theory, are needed to fill a gap. And we already attempt to keep people in the local area for as long as possible. The Navy has a home port division which will keep you on the same coast for most of your career, a lot of Army types will spend huge lengths of time in Edmonton, Shilo, Pet etc. and I see a ton of air force types who get 10+ years in the same area (sometimes at the same unit). Maybe all we need to do is do it better.
Maybe I'm wrong but I am very skeptical. The only people I have talked too who are for this are people who are in the process of being released and don't want to give up 80 grand a year and try and work in the real world. I totally understand their POV, I've never had a career outside the military and leaving the fold is scary. But every non-deployable body we keep, holds up a rear position and a promotion for people who can do the job. And unless that is addressed, this could be a disaster.
