SAN ANTONIO (AP) -

For five basic training instructors convicted in an Air Force sex scandal, their sentences of "hard labor" involve cleaning the base's dog kennels.
    
That's a far cry from the perception some have of hard labor as breaking rocks with sledgehammers. But an official at Joint Air Force Base-Lackland said hard labor is designed not just to punish, but to serve the base.
    
Nine former Lackland instructors have been convicted in an investigation of claims that instructors pressured female trainees to have sex. Their sentences have ranged from prison to hard labor.
    
There are few specifics on what hard labor can mean, but soldiers at different times have been required to pick up trash, pull weeds and clean.
