Finally cleared the Lv40 Mission and now I'm First Lieutenant of my GC! Thank goodness took a while and it was thanks to a 1 Tank and 3 DPS combo I manage to get it with some leveling.

Honestly this is kinda boring. Only did it for the promotion. Kinda wish there was more to it and I hope that the Squadrons can come with us on our dungeon runs in the future.
