After spending a bit of time looking for available flags in 28mm, I've decided upon utilizing Thirty Years War Swedish ones. More generic in nature, I chose to have them in both Green and Blue, because those happen to be the two main colours of my uniforms. I have selected flags for every unit except for my skirmisher one, which does not have a standard.
