Commendations - full list?

Hi,
Can someone tell me the order in which the commendations unlock? eg novice, proficient, qualified etc.
Also if anyone has a full list of all of them, that would be great, and now many kills etc are needed for each one

um, spartan hub, push up, click commendations, read

so far i have

novice
proficient
adept
expert
distinguished

hope that helps a bit -.- as for the numbers it depends on the commendation i believe.
