Per chevron reversed wavy Azure (Oriental Blue) and Or (Golden Yellow) in chief two muskets saltirewise counterchanged, overall an equilateral triangle point up Gules (Brick Red) bearing between three mullets with each point in angle, a covered wagon viewed from the rear of the second with a canvas Argent embellished of the third.
That for the regiments and separate battalions of the Indiana Army National Guard: From a wreath Or (Golden Yellow) and Azure (Oriental Blue), a demi-lion rampant Argent, holding in dexter paw a laurel branch Vert.
Brick red and golden yellow are the branch colors of the Transportation Corps. The equilateral triangle with three gold stars, adapted from the seal of the President of the Philippines, commemorates the Philippine Presidential Unit Citation awarded the unit in World War II. The three stars highlight the participation in three campaigns: France during World War I and two during World War II in the northern Solomons and Luzon. The covered wagon refers to the Battalion's transport mission. It also represents their home station South Bend as it was a manufacturer of the famous wagons which contributed so largely to the development of our Nation. The blue on the shield with the wavy downward bend partition (to "south") alludes to the curve of the St. Joseph River from which South Bend took its name. The crossed silhouettes of the muskets, adapted from the Infantry Branch insignia, highlight the unit's infantry heritage when it was first organized. The crossed weapons also symbolize military preparedness and underscore Indiana's State motto, "The Crossroads of America."
The crest is that of the Indiana Army National Guard.
The coat of arms was approved for the 190th Transportation Battalion on 13 November 2006.
