The MOD did say in their letter that a 'small number' of ranges/training areas are not owned by them so the ban/archive won't apply. As the ranges shown on the OS maps are very extensive it would imply the 'larger number' of areas will have the ban/archive applied.
I'm working with the GAGB team who are talking to the MOD to get their digital mapping. Once I have this and know what area is what I can begin the process of identifying caches and see how many will need archiving. Of course this would only apply to those caches listed on geocaching.com.
