From a PM exchange:

[quote]1. What is the definition of a "friendly IFF"?[/quote]
Any IFF that isn't in the "$Attacks:" list, unless this is overridden in the mission (by setting all teams at war, for example). [/quote]
This is not on the page, but is good to know considering it is referenced in the "$Flags" section, under "orders shown".
