XCOM Enemy Within adds medals which you can award to your soldiers. Another question covers how you earn medals, but I would like to ask what things I should consider when deciding who to award a medal to?

• Are any medals particularly effective for some classes? Are any of the medals wasted on certain classes?
• Do any of the medals combo well?
• How do medals work when changing a soldier to be a psy op or a MEC?
• Is there an optimum time to award medals? I'm starting to be given the option to award them when my roster is full of squaddies and rookies; should I wait until they are higher ranked? Or do some have less benefit for higher ranked soldiers?
