Check out Osprey's books. I'm not sure if they've got a book on the
modern Russian Army, but I think they have several on late Soviet era
stuff. Osprey is heavy on text, but it's pretty comprehensive. They do
have many pictures, but the highlight are the eight or so color plate
pages in the center, with explanations in the back. I've got a gigantic
collection of Osprey titles and they are a staple to most of my
projects.
You might also look into Europa Militaria books. They have some great
titles that include lots of pictures of live models wearing actual
uniforms and equipment. Though, I just did a quick check online and
couldn't find any titles along those lines.
Schiffer Publications does have a number of books on modern
Soviet and Russian vehicles, which also shows pics of soldiers
operating with the vehicles. Might be some good stuff there.
