I knew it! I built a 1/48 Patton when I was in my teens and everytime I watch (even today) Battle of the Bulge or Patton I could swear they used the M47...now you've confirmed it! It seems the only WWII movie from the 70's that tried to get it right was A Bridge to Far. They even have British Bren Gun Carriers.
Now back to the Photography - Go with the tripod! Even an inexpensive $30 tripod will work for table top shooting. I wouldn't be too concerned about the dark running gear (as I said, it was a nit!), because there is still full detail to be seen in the shadows.
Color balance is a function of the lights, background and camera. If you are using incandescent lights they will give an orange cast to a picture (without flash). Normal fluorescent lights tend to give a green or blue cast. You can get fluorescent lights that are "color balanced" to standard daylight (which is usually given as a color temperature i.e. 3200 - 3500 degrees Kelvin). Photographic strobes (built into most digital cameras) give the correct color as do regular photographic flash (strobe) units that attach to the camera hot shoe. Try to use a white, off-white or light grey background instead of blue, black or red. That way the reflected light from the flash won't be color shifted by the background.
Digital cameras usually also have a color or white balance adjustment. Check your camera manual for how to adjust yours. And of course there's always Photoshop and the like for manipulation within the computer.
