wow!!
that's a lot.
first make sure you have the blackhawks from BAS as well as the pavehawks or they won't work.
then, check the readme that came with the blackhawks as in there is all the code that explains how the AI does fast-roping and extractions and such.
I would advise you to read through them first and THEN go on these forums as there is a lot there. also visit the editors depot for basics about scripting so you know what the readme is talking about.
then also go to the addon depot section of the forum and find the BAS discussion thread in the addon discussion scetion. it's a long thread but all questions and answers have popped up in this thread or related ones. also the BAS staff are always there and helpful to answer any questions. After you read the readme and note down precisely what you're having trouble with - DEFINITELY give that thread a visit.
sorry that I don't "explain" anything as such but what you're asking is very broad - best to take it in stages!!!
good luck
