ARNG has stupid stuff just like RA; some same, some different. Thing is, you generally have to put up with it on the weekends and not so much rest of the month. Some of the drills are going to be a waste of time such. For example, having to do SHARP training every quarter and all the other mandatory training that you don't really have time to do. Really eats into real training time. One whole weekend will be spent qualifying. It will definitely be different than RA but I don't think it's that bad. Just don't go in thinking you're going to get to do all the high speed, low drag stuff you go to do on AD. You won't, at least not very much. You'll get to do it when you go to AT and maybe a handful of drill weekends, but RC just doesn't have enough time to do it like RA does. You also have to remember that RC doesn't get training areas and ranges as often as RA and most units have to spend some of their available time traveling to a post for ranges and TA's.
RC is definitely not like RA but if you have the mindset that you want to do the best you can and train Soldiers, you can bring a lot to the unit and really help them out. Wade through the BS but don't show up and act like you're God's gift to the Infantry. Keep your mouth shut for awhile and let your actions speak for you and the Guardsmen will be more likely to accept you. Remember, RC is still a good ole boy system in a lot of ways. Not nearly like it was before 9/11, but it's still there. Don't expect to walk right into a squad leader position either. A lot of times the leadership has been in the state Guard or even the unit for years. They might have E5's and E6's that are at 20 years or more. Not many, but there will be some. It's not as bad as it used to be; post-9/11 operations have thinned the herd a lot but there are still some legacy Soldiers out there.
Just like RA, RC units vary in quality and dedication. Some are good, some aren't. Hopefully you'll find a good one and contribute. I know how you feel about being out, though. I was in the IRR while I worked on my masters degree and I missed it. I got back in the Army Reserve after 9/11 and have done a lot since then. Been deployed, worked for GO's and taught ROTC. I'm getting near retirement now and I'm ready to be done but I know I'll miss it just like I did before. Give it a shot and see what you think. If you can do a one year enlistment, try that and then go from there. If you don't like it, at least you can say you tried it out.
Good luck!
