I'll probably do both if the first one goes well to be honest. I'd like to do the real life version and will do a bit of research, the film will probably be easier to reference though. I think the only thing I'm going to have trouble getting is a reasonably priced PT armour
I dont want to scrimp on this though, everyone I've seen on the internet has cut a corner somewhere and it really shows I think. Delta would probably be easier as there are G&P M733's available in the UK, any G&P m16a2's I've seen would have to be imported
