It's not like the army forces you to the job that they want you to do. No one finds themselves in a combat role by surprise. Besides, most military jobs are support based, like logistics or IT. I'd maybe recommend it to someone who doesn't have money for college but has an interest in something like computer science. But even then, the GI isn't as big of an incentive as it used to be since a college education doesn't really guarantee you a comfortable living anymore. I'd probably recommend most people don't join the military but it can be a good life decision as long as you know what you're getting yourself into
