Gary's Military Modeling Page is a great place to do some nice photographic research. There are links galore here, and he covers reenacting, modeling, you name it.
The most interesting thing on his site, though, is the 1/6th scale military models he builds. These figures are much like the GI Joes of old, but the uniforms and the models themselves are much more detailed. I think the Bayonet Duel is pretty gripping for a diorama.
If you want to see something different, this is the site to check out.
Fellow blogger Pith Helmet would appreciate this site!
