Dead, I dont think so. At least not the two guys to the side. That one behind the breach tho, yeah he just had his 'nads blasted off. The other two are still standing and that was a really flame heavy (low energy) explosion + the camera guy barely flinches when it goes off. Any shrapnel was most likely contained by the barrel, so only the guy directly behind the breach was at direct risk from that. Those other two are having a bad day, but they’re gonna walk away…

They ain’t OK, bub.

WHAT DID YOU SAY, COMRADE???

Most likely

Depends on the level of medical care they receive

So, yes. Very dead. Perhaps not quickly though.
