I was also there and served mostly aboard the Canberra as a member of the Royal Marines. Since i joined as a musician [ a bandy in RM speak] it came as a surprise to go off to a war. Amongst other things remember guarding several Argy pilots who came through Canberra's medical system as well as trying to bring them down with a GPMG from the side rail. Don't think i ever hit anything but the guys already ashore and digging in must have had a few scares!
I have a lot of flight sim experience and also quite a bit of music experience of all sorts [not just military] so would consider offering my services on the music/sound front.
Good luck with this project.
