Can anyone still serving or not serving explain "in laymans terms"what a P7 is? Having applied for a position in Afghan with an audit team via the TA, I was sent to Chillwell to complete a medical and administration phase before deployment. On the medical phase I was diagnosed with hearing loss and P7'd?,being given home commitment only. Can anyone explain what the grade means and what % of loss of hearing this implies. Having served in the regular army during the 80's-90's, the ear defence wasn't what it is today, hence the hearing loss.
