The military will provide you with all the training you need, so that you learn to do it "their way." However, being familiar with the terminology can't hurt! Not to be the one to throw a wrench into things, but, not everybody qualifies for military service. Sometimes people have medical conditions that were not previously discovered, such as an enlarged heart or something, that disqualifies them. Or, their personal life changes, and, perhaps a parent suddenly becomes ill, and they want to stay close to home. So, while you are going forward with your plans to join the service, I would encourage you to think about, "What if?" Have an alternate plan, just in case, and pursue an education path that will allow you to follow the alternate path. And in the meantime, start reviewing ASVAB study material and talk to a recruiter!
