I'm sure you guys have probably seen this photo before. But I wonder how many of you know there's a second photo of these same soldiers from another angle?

I was wondering what people could tell me about the uniforms these soldiers are wearing? I am not great with that sort of stuff and you all seem to know a lot more. I've been working on a video project for a while about these photos. The location of the photo is a hot debate among Civil War history nerds and I have it pegged and have been researching and nearly completed with my project after about ~4 years of it being somewhat of an obsession. I'm pretty certain their unit based on their location. But i'm just curious what sticks out among their attire.
