taking no prisoners

Utterly without compromise

Taking no prisoners describes an aggressive, uncompromising approach that shows no mercy to opponents.

The military origin is literal—capturing no enemies, killing them instead.

The figurative sense dominates: Her cross-examination style takes no prisoners.

It suggests ruthless effectiveness, someone who pursues goals without softening for others' comfort or feelings.
