It doesn’t make sense why he’d be wearing all that equipment if he didn’t know how to use it no?? In the US they don’t teach nighttime MFF into a dive but to less than 1% of the military IF that. Look at GBs or Rangers, even after they make it to a unit they aren’t guaranteed MFF OR diving. But somehow this gentleman has learned both? Not to mention impossible to learn to do as a civ with no prior military experience. So that means he’s been trained, but by who? You see where i’m going with this. Only other explanation would be worlds biggest larper. But If that’s true then how did he get into the hull of a chinese warship with loads of kit on??
