Commendations are split into five separate sections:
There are 125 commendations available at the game's launch which vary in difficulty. You can view the requirements and your progress towards incompleted commendations by clicking through to each of the categories and scrolling down. You can claim any completed commendations by scrolling through the list and holding
to claim it
Under the summary sections, you will see the total unlocked out of 125 and an activity feed which will list any you have available to claim or a progression % for your closest ones.
You will receive 10 through natural progression during the game, so don't worry about trying to unlock this achievement early on or attempting to grind for specific commendations.
