to bring on the heavy artillery

e.g.

Also ich weiß nicht, wenn es laut diesem einen vorigen Leo Eintrag "to bring out the big guns" heißt, müsste ich ja schreiben "They often bring out the big guns in order to get their clients' attention", ja? Klingt doch total seltsam!! Oder "Heavy artillery is often brought in in order to get their clients' attention".

:/

They often roll out the big guns to get their clients' attention.

They often bring on the heavy artillery to get their clients' attention.

Beide sind möglich.
