I'd just like to add my tuppence worth here. I can tell you on absolute authority that the injuries suffered to this young woman were not caused by big- standard drill and marching, it was the march up and down Armoury Hill each day, with webbing and Bergen, that did it.
Unchecked - was the issue the load carried or the incorrect use of Bergen/webbing? If the former, you may have got to the bottom of why MoD succumbed with high awards, because it is well known that the loads carried during training were agreed by Arms Directors using a vague wave of wet fingers at a meeting in 1997, but no-one was quite sure where the figures had originated nor if they were based on any methodology. The programme that was mean to to formalise this using scientific means, didn't, and ever since MoD has been hoping nothing would happen. A well known MoD risk reduction strategy!
