Each year on November 11, Americans observe Veterans Day — a time to honor all who have served in the United States armed forces. The holiday traces its roots to the close of World War I and the signing of the Armistice  on November 11, 1918 that ended fighting on the Western Front. Originally known as Armistice Day, the holiday has evolved to recognize veterans of all eras.

In honor of Veteran's Day, we spotlight a World War I Balloon Observer Uniform that is on display as part of the Nevada State Archives "All For Our Country" exhibit. The balloon observer's duty was to ascend in a hot air balloon to identify the location of artillery fall during combat.

This uniform was worn by a U.S. Army captain, specified by the two metallic rectangles embroidered on his cap. The half wing insignia on the left breast of the jacket signifies that the captain was a hot air balloon observer. The drab olive wool service coat is displayed with a Sam Browne belt and garrison cap with red piping. The jacket features Maurice Bourbon & Paris buttons which suggests that the uniform was custom made in France circa 1917-1918. 

The Sam Browne belt features a narrow strap over the right shoulder. Originally, the belt enabled the wearer to carry and easily retrieve his sword; during World War I it facilitated carrying additional gear such as a pistol. The garrison cap is also known as a flight cap, wedge cap, or field service cap. When not worn, it was folded over the belt.

This exhibit offers a fascinating glimpse into the experiences of early military aviators and the technological innovations that shaped modern warfare — a fitting tribute to those who served then and now.
