Folks, don't try this at home.
According to a HuffPost translation of the video, which the Telegraph reports originally aired on state-owned Chinese Central Television, the troops are practicing "explosive package passing."
"A lit explosive package is sequentially passed among six soldiers, to test their ability for close coordination and psychological preparation," the reporter in the video says.
The soldiers count to six as they pass the explosive around the circle before throwing it into the hole.
According to the the Telegraph, this particular exercise took place in December at an exhibition in Hong Kong.
But this video begs the question: real or fake?
As YouTube commenter "ClaimChowdah" pointed out, at around 19 seconds into the YouTube video a soldier appears to drop the "package" at his feet, while the explosion comes from the hole, which is clearly a few feet away.
What do you think? Too good to be true? Watch the video above and let us know in the comments.
