Also, you have to have some understanding of your weapons. Are they fire and forget, to they require illumination (and is it by firing unit or can it take an outside "signal"). Or are they dumb. That information is in the database. And as wood1 said, WRA has a huge bearing on what attackers will do on the attack. You do have to manage your own EMCON for the most part. Note that he was demonstrating something else while the attackers were in the area to attack and not actively managing what was going on there.
Additionally, there is a manual for C:MANO, and a fairly extensive supplement on line at warfaresim.com that covers many (admittedly not all) of the additional features that have been added. The manual is located in the Manuals directory of the installation and there is a link right there to the online supplement.
The manual for CMO has already been made available. It's good reading and besides a listing of how all commands and options work, there is quite a lot of helpful information on why things work the way they do, and the effects that choices make - somewhat similar to the old Harpoon strategy guide in giving some hints as to how to employ systems. Good info. Well worth reading the whole manual (doesn't take that long - it's 280 pp, but they are small pages).
Kushan's CMO stream was pretty quick and dirty, obviously intended to show many of the features and options. It didn't appear he spent a lot of time before running it deciding what he wanted to do and setting up, or being familiar with platforms and weapons. No criticism intended - that's not why he was running the stream. It wasn't a demo of how to play that scenario, but a demo of CMO features using a reasonable sized scenario and he did a good job of that.
If you haven't yet I'd suggest reading through the announcements for CMO, the developers interviews, and the manual. Your answers are there.
Can't tell what your issue has been with tankers, but it works for me. Best way to get questions answered is to post a message with a save in the forum. You'll find that there are usually several people who will download and take a look for you to see if they can figure it out. Plus the developers.
Hope that helps.
