Oh right, the spike grenades. I figured it out. Also it has a massive cylinder part, I can reach the middle of my back let alone latch onto a long stick protruding from it. I guess I'll just pull it off :O

That is if said Elite Soldier didn't hear the latch open, or everyone else noticing someone dangling from the ceiling. I'll respond to it, but as it was an autohit I'll take my time.
