The forces shifted the apprehended militants for interrogation to an undisclosed location.
They were later handed over to police and a case was registered against them. The condition of the injured Taliban men was yet to be ascertained, a security official said.
Afghanistan Taliban have been active in Zhob district whose borders extend along both Pakistan's tribal belt and neighboring Afghanistan.
