These will be 'options' from the PR10 work. If you have never been involved in options for these rounds, something like this might be a bit of a shock. Pretty much every option has to be put up for review - no matter how unpleasant they might be - with the numbers next to them. The grown ups can then look to see what is what, and make decisions from there.
I'm quite sure the RN and Army are doing exactly the same with some pretty big calls in their options.
