The Army doesn't pay well anymore, I remember a while back a couple of homeless people on the streets that claimed that they served in the Army - Is this where you'd want to be after you served your country?

No. I don't think it should be compulsory for citizens to serve in the Army for 3 years. What about minorities? As long as their are parties in existance like the BNP, you won't get large numbers of black and Asian people joining.

The sitiaution is different for countries like America, though.
