I'm currently looking at (among other things) joining the Grenadier Guards. I was thinking of going in as a soldier but at college I am getting and predicted good enough grades to go officer. The problem is that I am not posh. If I went in as an officer would I be immediatly alienated for not being 'one of them'? Also all my mates in the army are all rankers and I don't want to alienate myself from them or have to pay huge mess bills which (as a not-really-middle-class bloke) I would not be able to afford.. Any opinions?
