Hey thanks for the tips, I thought I'd report back with how things went for the first few matches I CO'd on!
I did what you said, and just dove in. I jumped on and spoke to each squad individually about what I was doing (learning, watching, and aiding), and stayed on top of requests / markers and objectives that each squad was attempting.
There were a couple matches where, because I was feeling ultra newbish, I think I talked
too much and as a result, wasn't listened to. Frustrating for sure, but a great lesson. Nobody out there, SL wise, is looking for me to be a chatter box and apologetic, they want me to get my question out and be done with it =p. So now, I typically think out everything I want to say first, trim the hell out of it, and then ask the SL. Sometimes, I don't have the privilege of time like that, but I always make sure to say it in my head or out loud first before contacting the SL.
That was, to be sure, radio basics, but it was something great to remember diving into the next matches. I got a great response when I kept things nice and short.
Last night, I got ripped apart, every single map. I'm not entirely sure what went wrong, but the entire time I got like, one or two squads communicating back what they were seeing, with targets and voip. Snipers were great for that, but most SL's in last nights maps weren't down with reporting in with me. I really didn't learn a ton about movements, I just saw a lot that didn't work, but without the squads communication, I had no real idea about why it didn't work.
I have an idea that they weren't really regrouping. I saw a lot of lone dots, ambling around by themselves. I even had a Sniper / Spotter squad... with just one sniper, and no spotter. I tried to get him to join the forces, but he refused. It worked out though, because he spotted every single back hack before any of the other SL's would radio in about it, and we got a lot of forward notice on well... losing, ha!
Admittedly, I was nearly dead silent most of the time, frustrated and intimidated with the lack of communication. That didn't really help anyone, so I'm sure I could have done more.
Today though, I went to Chicago's Kashan only server, and dove in. It was great because I had so many assets to play with, and the SL's on Chicago's servers tend to be extremely well oiled machines. It was largely on auto pilot, and naturally, the team won, 3x in a row!
I followed your advice though, about just keeping squads updated, answering queries, and kept barking orders to a minimum unless there was dire need (like my supply / transport choppers getting chased, and we had a jet in the air... that was a rather immediate and present need to get a jet to help out). The SL's were great, very chatty, and constantly kept me up to date. We found FB's, took flags, JDAM'd, and all had a great hoorah at the end when we actually took the last base.
My favorite squad was definitely the tanks on Kashan, and from what I've read thats pretty king there. But right there next to them were the transport choppers + the Inf Eng squads. We had 3 FB's by the end of it all and were streaming men in to a couple objectives at a time. Again, the SL's were pretty on it, so the experience was enjoyable.
Anyway, enough excited babbling. Great learning experience, and I'm definitely hooked as a CO.
So, on the with the learning and note taking, and thanks for the advice, gave me the stones to just get in there and do it!

I can't wait to start getting some solid tactics and plans in order.
Oh, one question, is there a screenshot of the CO's screen that explains each kit / vehicle icon somewhere on the web? Sometimes the SL's would throw jargon my way that I wasn't familiar with, or would ask for a particular vehicle support that I wasn't sure of, and I'd love to see some kind of labeled icon screenshot I could refer to.
Thanks tons again!
