When DERP and explosives mix, it’s a deadly cocktail:
I don’t know much about grenades, but I’m assuming he either let go of the lever way before he dropped it (running the time out), or else it was faulty. All I can say is it’s lucky it was slightly in the water, because otherwise it probably would have killed them both. I’m assuming it was a concussion grenade, not a fragmentation grenade. Considering you can’t control the direction of the fragments, i’m pretty sure no one would be dumb enough to use fragmentation grenades.
There’s a “In Russia…” joke in here somewhere… how about “In Russia, fish kill YOU”
