A prison guard is someone who works as a guard at a prison. Duh! Their gender is usually based upon which type of prison they are employed at. Female detention centers typically (though not always) employ female prison guards, while the sausage factories hire people with penises. That's just how it goes. A prison guard works for a warden and is typically charged with monitoring the actions of a facility's inmate population, doing bed checks, hosing them down, breaking up fights, etc. In the event of a break-out, a prison guard is expected to pursue and recapture escaped prisoners, which is why most prison guards are armed.
