8/14/17: AUGUST 15th is the start of season 3! Those of you who played one match during season 2 can now unlock this achievement (hopefully)
Update! As of today may 16th 2017 this achievement is now available! I've heard that if the achievement doesn't pop you may want to play a match against AI or PVP the deploy war assets. I can confirm that's how it worked for me after returning to the main menu if it doesn't work I am not sure what else to say...
You DO NOT need the season pass to obtain this achievement.
For many of you (Like me) who are wondering when the next season starts... Ubisoft has announced that MAY 16th 2017 will be the start of season 2 thus earning you this achievement IF you participated at least once last season by playing a match against either CPU or PVP and deploying war assets at the end of the match.
Not sure why I'm getting all these negative votes but leave a comment so I can try and assist you. It's not my fault your achievement isn't unlocking... I've said everything you're supposed to do in this guide in order to unlock the achievement.
