How to Get a 3x3 Container on Delta Force Operations

Season 3

The seasonal quest line titled "Season Mission: Firework". You can get lots of 1-3 day passes by completing the quests and once you have completed them all you will unlock the 3x3 for the whole season. We have been grinding at a reasonable pace (gaming after work) and have never ran out of the 1-3 day passes so far, essentially unlocking it even before completing all quests..

Why is a bigger safebox better?

Bring in purple/gold ammo/repair kits without risking them. Get big reds out of raid with 0 risk. Improve your rat run efficiency.

Collector Quest Loot Tracker

There is one set of quests called the "Collector" quests that require you to submit certain items that you have found in raid, you're not able to buy them on the auction house to submit.

You can and should start looking for all of these items and storing them in your stash so once you unlock the collector mission you're ready to submit them.
