AI Amphibious Assault help/request

[Spades_Neil 1]

I'm trying to script an island defense mission on Utes, and I need a bit of help here.

Here's what I'm trying to accomplish:

- Several AI-controlled AAV7A1 spawn in the water and drive to shore while human players defend the island.

- AAV7A1 drop a team of marines when they reach shore, and advance inland together.

- Several UH-60 helicopters that land on the beach to drop their passengers and take off again to circle the area, similar to the AAV7A1.

- Variable amounts of vehicles per wave. (I want to be able to know how to change the number so I can edit if too many or too little attack at once).

^ That stuff is most important. The rest below is stuff I'd like to know how to do correctly instead of the way I do it.

Here's a pretty picture for your amusement.

Now, I also want these waves to spawn with increasing difficulty. For example, maybe the first wave is just one AAV landing on the beach and a single group of soldiers going inland. The next wave is two AAV. Third wave is two AAV and an LAV. Fourth wave is two of each vehicle. Fifth wave has three of each vehicle, and now a single UH60 Helicopter is added to the mix. Sixth wave adds a second UH60. Seventh wave adds a Cobra for air support. Eight adds another Cobra. Nine adds a pair of F35. Ten triples all the attacking forces. This might not be exactly how I do it, but you get the basic idea.

How I'd do it: Use whatever help is given to me and copy/paste it a gazillion times and delay them from entering the mission. I want to know the correct way of doing it that is more efficient.
