Challenges List: Extra Credit / Tour of Duty

A List of all Assault Ops Challenges (Including Operation F)

Introduction

This is a list of all 90 mission specific assault ops!

I hope this might be of use to at least some people because honestly, clicking through the in-game list makes me sad
(also I guess it saves from having to Alt-Tab / quit the mission to check the specifics each time!)

Tip: In some cases it's quicker to get kills towards an objective then quit out and re-start, you don't have to finish the mission!
(Thanks to user /id/agof !)

Each operation has its own section for ease of navigation.


The format for each mission goes like:

Operation-Number

1) First Ops Title [Reward XP]
• Description of the first mission specific

2) Second Ops Title [Reward XP]
• Description of the second mission specific

3) Third Ops Title [Reward XP]
• Description of the third mission specific

There is also a section at the end dedicated to images of the targets mentioned in the challenges, in case anyone needs some additional guidance!

(It's my first guide so I'm bound to make some silly mistakes: any criticisms/comments/corrections, please just say so below!)

Whatever works best for you :)
