Won every Campaign level as a Militia pilot

The IMC and Militia campaigns consist of nine chapters (aka matches) and you will need to win each of them for the "Elite Pilot" achievements, while simply finishing them will unlock "Pilot" achievements. The chapters are below, and the game types you play in each are also listed. The campaign is basically regular MP matches with some story and cutscenes woven in.

The Refueling Raid (Hardpoint)

The Colony (Attrition)

The Odyssey (Attrition)

Get Barker (Attrition)

Assault on the Sentinel (Attrition)

Here Be Dragons (Hardpoint)

The Three Towers (Attrition)

The Battle of Demeter (Hardpoint)

Made Men (Hardpoint)

After completing both sides of the campaign, you will be able to choose a specific chapter to play. The side you get will be random, and it is rare to get Militia for some reason. Just quit and search again if you don't get the side you need.

The game does not keep track of which maps you've won on, so make sure you copy this list and mark them off as you go or use the Excel/Word files linked in the Road Map.
