My Father did not pass the medical for the forces in the early forties, he was grade 3. he never spoke about why, is there any where that I can find out, now after all this time. thanks.
I have got my Fathers service record but that was in the 1st war,100 years old. The second WW is too recent to give out records,but as a relative the MOD may tell you ? ( I am assuming you mean UK forces)
