A muzzle brake (not break, unless you actually broke it) serves to reduce recoil by turning some of the gasses and directing them to the rear.
A compensator may do that, OR serve to compensate for a tendency for the muzzle to climb- so it diverts gasses UP, pushing muzzle DOWN.
A flash hider serves to hide the muzzle flash from the shooter's vision- see the Lee Enfield jungle carbine.
There is also a flash suppressor, that serves to reduce the muzzle flash as seen by others.
What we have here is... failure- to communicate.
