TG-specific framework sounds nice, and I do think that something that should be added is, apart from my Mr.G-C above suggested system for handling JIP, also should include a way for squad leaders to teleport all their team members to their location, so that it can be used to get JIPers into combat on maps that lack in logistics systems.
Another variant of JIP system would be to as above put all AI into a group of their own to let people JIP into them, and then use the Team Status script to manually join groups that one is assigned to (which would usually be the job of the 2nd in command of the platoon to sort out)
