Watching Aliens again, I know every scene pretty well, but I noticed something new.
The smartgunner "Drake" seems to have some sort of ornament / decoration. I spotted it in two scenes, once it was hanging from his USMC cap, and in another scene it's hanging from the end of his smartgun.
It doesnt look like part of the smartgun (and Vasquez doesn't have the same thing on her gun).
If it was earth in the present day, it reminds me of the sort of ornaments you can buy as a tourist in Mexico. Maybe there is some cultural or religious connection, but this is 2176, so I wouldn't know.
What is it?
