I used to be in the military long ago. You will be doing a lot of training on a variety of topics though. Weaponry is just one of many. Land navigation is also very important to know, depending on what job you go into you may be using it quite often. Instead of a GPS, you will have a map and compass. It definitely helps knowing how to use it. Very often It was used for my former job. Just carefully think of what you end up getting into when you go through with it. I have made life time friends from it and it was worth it. I joined right after high school myself many years ago. After I completed my contract, I used what I earned to pay my way through college. Not having to worry about student loans was definitely worth the time spent. There are many other things you will end up learning depending on the choice you make and where you end up being stationed. After you get to your first base, there is even more to learn that they will be teaching you. Get into the habit of being at appointments scheduled at least half an hour early. The military works a lot differently than what many are used to. Being just on time is considered being late. That will be said to you a lot I am sure. it will definitely be an experience though that you won't forget.
