It is possible but extremely rear. It also depends on what type of unit you are in and your commands willingness to send you. In my 10 years in the guard I have heard of only one enlisted guy to try and he didn't make. More than not they aren't ready. You will have to go to RTAC first at Benning to even get a shoot at Ranger school. Also, you should come with a functioning knowledge of infantry operations. That is pretty rear to find the Guard.
You should have a chance "at some point" over your career to go Ranger. The best gauge of when that might be is with your Chain of Command. The thing with being in the Guard is each state may only budget to send but a handful of people every year, and they obviously want to send someone who's a lock to earn that tab. The best thing for you to do now is make sure you maintain as close to a 300 on your APFT as possible and master your 10 level skills. If you really want Ranger, you'll have to stay in your NCOs ear about it, that may take months, may take years. Just don't disappoint when you get the opportunity. Good luck.
