Evolution Of American Army Uniforms

I came across this on Twitter a short time ago and was touched by it... way cool, but kind of melancholy in an existentialist sort of way as one is reminded of how ephemeral everything is as change is the only constant. The Roman uniform changed over the course of human history as did the uniform of soldiers of every great civilization throughout history. Someday we will be gone and people will remember our warriors in like fashion.
