i was actually thinking the same, thats why i went to look it up, my guess was vibranium, but it doesnt mention it in the wiki.Thanks. I was just curious if it's made from one of Marvels fictional metals, like Adamantium, Vibranium, Carbonadium, etc. No info about that I guess.

going with the secretary of defense, might throw us a curveball and make it nick fury tho
