'The MoD said the RAF had now reviewed its recruit training practices to reduce the risk.
The women told the Mail on Sunday they had extended their strides to 30in (76cm) over several weeks while undergoing basic training.
RAF official policy now states female recruits should not be expected to extend the length of their strides beyond 27in (69cm).
The paper reported that lawyers for one of the recruits claimed the Ministry of Defence (MoD) had accused the three of exaggerating their symptoms during the five-year legal battle.
As well as marching in step with male colleagues at RAF Halton, in Buckinghamshire, the recruits claimed that carrying the same heavy packs as males had also contributed to their injuries, the paper reported.'
Love the claimed! Assume because wasn't in the claim brought, so not proven HOWEVER they won, stride rule came in for women, it's pretty bleeding obvious heavy load would make it worse!
Anyway good rules were changed.
