Teachers today vowed to oppose military recruitment campaigns in schools that are based on Ministry of Defense "propaganda".
The National Union of Teachers (NUT) voted to back any school staff who want to boycott Armed Forces recruitment campaigns.
Delegates at the union's annual conference in Manchester lined up to condemn the tactics of the MoD in targeting teenagers with "misleading" information that they said glamorizes war.
The union backed a motion committing the NUT to "support teachers and schools in opposing Ministry of Defence recruitment activities that are based upon misleading propaganda".
Paul McGarr, a delegate from east London, told the conference: "Personally I find it difficult to imagine any recruitment material that is not misleading."
He said: "Let's just try and imagine what that recruitment material would have to say were it not to be misleading.
