I know a lot of Ranger and Green Beret units carry Tomahawks. But those are approved for use, especially because they can be used in fieldcraft (Chopping firewood, building shelter/cover) if needed.
They apparently WEREN'T authorized for this Seal Team, though. It was violating their equipment protocols to seem cool and showy-offy.
This is correct and like a bunch of children the tomahawks ended up being a psychological contagion for the SEALS. They reportedly ended up mutilating corpses with them.
Apparently, they also canoed the shit out of UBL’s corpse like a bunch of speds.
Look up “gay chicken”
