Saying that for the Horizon Islands, would be saying the other factions should have their own mod as well. I would think it's best it stays as part of a collection alongside all the other factions. But if they want to take full consideration on that, Would gladly take it and play it! Would be amazing to have an army comparable to other Pacific Island countries. That said, since said army is surrounded by a lot of water, it would be best to at least have a boat unit (vanilla one at least) along with the faction for maritime purposes, it's just one less hassle when placing them down in Eden or Zeus.
Thanks.. I will try to add an equal amount of less each time I add some more... ;)
Speaking of more.. here's a site 3km north of the runway. FIrebase/AA site with overwatch positions on surrounding hills.
