An apparent dispute over command decisions led to blows between a Pennsylvania fire chief and a firefighter at an incident Sunday.

Stowe Township Fire Chief Matthew Chapman, who established command at a house fire, was in his vehicle when the argument started, according to CBS News. 

The Preston firefighter was yelling profanities at the chief, and started to walk away. That's when Chapman charged at him and punched him the face. Officers broke up the fight. 

The chief told the officer the firefighter had been questioning him about his decision making. 

He has been charged with simple assault and harassment.
