urgent!!! help how do you make 2 teams to attack eachother

heres what you do, you go to the top where it says"scenario" then go to "force properties..." click on "add force" and add the number of teams you want, then click on the player color you want on a certain team and drag them to the "force" for example say u want player 1 red on force 2, you make a new force, then click and hold on red and drag it to force 2. This will make it be seperate teams and make them be against each other
