Dog Tags in a Facehugger?

Given you're talking bout the picture above, i don't see any dog tags.  Neither did I notice flying tags in the trailer. 

In case of eggmorphing occuring in AC, I can perfectly imagine them ending up inside an egg.

This is where I see dog tags flying from the egg

Something hanging from the guy looking at the egg. Given the coiled appearance at the upper half, I'd wager an earpiece.

One thing its not: definitely not dogtags flying out of an egg.

It happened so quickly I am not sure it is any kind of piece of identification. I am wondering if it was part of the actual mechanism with the prop?

I've blown up the image and it is definitely a chain with something attached.  Disc like.  It could not have come from the man being face hugged since he was not "hugged" yet.  Looks like dog tags to me still.

I think this is a headset not a dog tag.
