Single Player Map

[Blade]

For the tanks thing, you need to create a taskforce that contains the 5 tanks, create a script that has them do what you want them to do and a teamtype that pulls it all together. The you need a trigger that creates the team, but NOT the one that says it makes the team automagically (there are at least 2 "Create teamtype" triggers IIRC). This should make the game recruit the 5 tanks into the teamtype and make them follow the script.

For the AI, there is a begin production trigger that needs to fire, again IIRC. Sorry I don't have FA2 on this comp, so can't get the exact action numbers for you.
