United States Army 305th Military Intelligence Battalion Unit Crest (Ad Arcana Tutanda) Criteria: This is the Unit Crest (Distinctive Unit Insignia) for the 305th Military Intelligence Battalion. The motto on the crest loosely translates to "To Keep Official Secrets Safe" which reinforces the overall goal of the group. Unit Crests are worn on the Epaulets of the Army Class A Uniform jacket. Note: Sold in pairs (i.e., if you order a quantity of 1 you will receive two Unit Crests).
