At first blush, I was reminded of Tom Clancy's novel and then video games Rainbow Six, a fictional multinational counter-terrorist organization named Rainbow. I guess the "Six" comes from Seal Team Six. Since the book came out in 1998 and this movie was in 1982, do you think Clancy may owe some credit to Megaforce? And it even feels like Delta Force (1984) with Chuck Norris and Lee Marvin may have borrowed a bit, particularly the vehicles.
