If you scan them you will always see CMDR in front of their name.
Morgan is correct, but don't rely on the hollow square. It's been buggy for a while. A human player will have CMDR in front of his name. That's the most reliable way to confirm.
Anytime we are having fun in a CG, it's a good time to heighten your awareness of your surroundings. It's easy to just start firing at ships in your proximity at a combat CG and you could accidentally fire upon a commander. If the RES is busy with several commanders that aren't winged, I suggest winging (more fun anyway!) or leaving the instance and playing in solo or a different private group.
On Saturday, The Dead Meat and I were in the RES for the CG, winged up and having fun.
Three commanders dropped in, and we chose to switch to my private group to avoid kill stealing or any friendly fire incidents. Easy peasy.
