Armored Core 3/Silent LineEdit
Irregular Ravens appear on several missions on the game.
Pre-Armored Core 4Edit
Irregular Ravens appear in different games throughout and are usually referred to as independents. This category is expanded further and includes Ravens who fight for warlords.
Armored Core 4/For AnswerEdit
Irregulars are generally rogue NEXT pilots like Amazigh and Sus, or Roy Saaland and Buppa Zu Gan in Armored Core: For Answer. Most companies want them destroyed because they can cause severe disruptions, and a NEXT that they can't hire is a very dangerous thing to them. Independents are a separate category now encompassing Lynx who do not have an affiliation with any company but are registered with Collared.
