This is an airborne scrap of a seatbelt. The vaporized bit you can no longer see was attached to the impact fuse on a variable-yield anti-tank warhead.
This is part of the tank's hatch. It is the second largest piece remaining of the tank after that warhead went off.
Here is another scrap of seatbelt. It was briefly clutched in the hand of the noble idiot who attempted to rig it like a pull-string firecracker.
And her is the noble idiot. His charred, now-useless uniform protected him from the nearby blast he deliberately triggered.
Okay, so far, so good.
