Upon viewing the piece the first time one is indeed impressed. If not frightened.
Six warriors (faces blackened for that Jean-Claude Van Damm effect) handing a smoking grenade to one another as it's about to explode? Those guys have nerves of steel!
Only two problems: Watch closely and you immediately notice that (1) that grenade isn't the kind of grenade any of us (civilians anyway) has ever seen before (it looks more like a harmless smoke bomb), and (2) when the "grenade" is passed around the second time, the last Ironman wannabe drops it at his feet - about two yards from where the "resulting" explosion takes place. Which means the explosion didn't result from the "grenade" going off; ignition was controlled by someone elsewhere to take place after the the little wieners leaped out of the way.
Nice matching outfits though.
Yeah, color me scared, Wang.
