Personnally, I think he's making an error.
He should opt for a Corps and get a trade, Farrier possibly or Chippy in the RE. He aint gonna be King just a Gwar so rather than waste his life like his uncles (and his Dad, whoever that was) at least he'll have a purpose and be able to help out around the estates doing the horses feet or a bit of renovation in his Granny's houses.
