Forces Memorial

I've been looking over the new Forces Memorial website, given the fact it has just been opened by Her Majesty this morning. The website states that this memorial is different to other war memorials because those who have died whilst in training have also been included.

Something close to my memory of serving were the terrible events at Deepcut, I expected to see that those who died at that awful place were suitably remembered. This doesn't seem to be the case, whilst their names are recorded in the Roll of Honour, they are absent from the War Memorial itself.

Could someone in know, please educate me as to why this is the case?

Whilst I don't pretend to know or understand the the events that led to the deaths at Deepcut, they were all still serving soldiers and in my opinion, should be remembered as such.
There's a couple of blokes I know who died in suspicious circumstances and their names are recorded in the same way, Memorial No, Roll of Honour Yes.
I seem to remember that something was said by the commentator at the
service that there were a lot of names still to go on and that they had been
delayed in adding those names because of the completion of other work and
by preparations for the service.
