301ST ARMY SECURITY AGENCY BATTALION
Distinctive Unit Insignia

The bat, a night flying mammal whose activities are shrouded in mystery and secrecy, is used to allude to those aspects that apply to the surveillance function of the Army Security Agency Battalion.
The distinctive unit insignia was approved on 20 May 1966.
