Q: I am 18 years old and will be completing my schooling this year. I am considering joining the army after I matriculate. Initially, after my training is complete, I will serve a certain amount of time in the army and may even be called upon to fight for the country (as is happening currently, where South Africa is fighting in certain other African countries).
My idea is that after some time, when I have sufficient training and experience, I will leave the army and become a mercenary (a soldier for hire). There is a great demand for mercenaries, especially in dangerous countries such as Iraq and other war-ridden countries like the African countries suffering from war lords, etc, and this profession is extremely lucrative.
Is this profession permissible in Islam?
