Ok, second night with COTA and with a very greatful help of Markshot and others, I think aim getting the grips on this. I did the tutorial #1 with axis this time around and got a marginal victory. The allies gave me a hard time, but I managed to hold on. I lost one unit and had to give up on two bridges, but it was worth it for the cause. I managed to blow up the main objective bridge, so that gave me some time. That also distracted them to head for the Komma bridge and break my lines and loss a unit. I cant get in to details because besides beeing a newbi, I dont know all the names yet [:D] I had a great time folkes, just sorry I have to send a regards letter to my KIA unit commander.
Here´s the inicial battle layout a bit after start:

Here´s the end of the battle:

The marginal victory:

I cant say aim learing this at a Ligioneri pace, but at a Regulars pace... Thanks for your kind help everyone [;)]
