I thought about this for a while but decided against it.
My dad is in the army and is friends with the guy incharge of the veterinary corps, and I asked my dad to ask him stuff for me.
The "Army" activities aren't a regular thing. It's just a couple of weekends and something like a few army training camps during the summer (usually abroad in places like cyprus), when you've not got uni. You get paid army pay for doing these too (which ain't that bad pay), so it's not that much of a big deal unless you are quite unfit.
The pay coming out of uni and straight into the corp is quite good too. I can't remember exactly what it was, but he definately mention it was higher than the usual amount (I think it was in the region of 30k or just below).
You do have to do a minimum of 4/5 years, though, which is a drag, and it's really only dogs and horses. BIG catch: in the first 2 years you WILL get shipped to Iraq/Afghanistan for the horses/dogs there. He told me it was a certainty. No ifs. No buts, unless things change by the time you graduate.
That's what put me off. I wasn't willing to sign away 5 years of my life + some weekends + some holidays just for an extra couple of grand during uni.
Bring on the debt!
My dad really wants me to do it (being an army buff, himself)and was saying things like "but you'll get to go abroad loads! It's a great experience!" but it's just not for me, i'd rather be in control of what I do. If other opportunities come along, and i'm stuck doing that, i'm stuck in a rut, so meh.
It's really popular with loads of others, which is why they only take on such a small amount each year. I think they do a few scholarships, and also take on a few graduated non-scholarships every year. If it's definately what you are wanting to do after uni, then go for the extra money.
