I though UKF were making the Starstreak HVM equipped Stormer so I left it to them. They know more about the muddy tin cans than I do.
I really dont know much about it. I never came across it in my varied careers so the best thing I can do is point you at http://www.army-technology.com/projects/starstreak/
Besides I think i know someone making it. I'll ask around.
