I will just jump in here, Almost all the scripts people do, generally just copy and past from other people, who write scripts for the actual game, if you Google what your looking for chances are you will come along some of the arma 2 moding, pages, they have alot of info and tutorials on how to do allot of things, like calling in artillery strikes or spawning LHD(aircraft-carrier). I dont have any links since I generally just Google what i'm looking for a brows threw sites, that have the info i'm looking for.
I know that telling you to use google is not really help full, but that really is the best way to search for the answers to your questions. I often find that just copy and pasting code together gets me just about whatever I want. Most people just read other peoples code to get an idea of how it works, if you can't read code, you might want to start learning how to do it.
