The Allied Forces and Belka were negotiating a peace treaty to end the brutal fighting. However, many Belkan militants refused to accept the treaty and continued to fight. In response, the Allied Forces sent a few mercenaries, including the legendary Galm Team, to deal with the threat in a top-secret mission.
The remainder of the rebel forces had holed themselves up in Anfang, deploying land, sea, and air units. Similar to Offensive Campaign No. 4101 and Operation: Dynamo, Operation: Broom was split into three smaller operations.
Mars Strike Team
The Mars Strike Team was tasked with taking out enemy vessels and adjacent surface troops positioned along the coast.
Mercury Strike Team
The Mercury Strike Team was tasked with destroying the remaining surface troops, as well as some fighters that were using Anfang's tunnels as makeshift air bases.
Jupiter Strike Team
After Mars and Mercury completed their operations, the Jupiter Strike Team would engage all remaining fighters to establish air superiority.
With the defeat of all of the rebel forces in Anfang, the Allied Forces believed that they were done fighting and didn't have to worry about any more Belkan resistance. Now that the peace treaty was signed, they could stop worrying about fighting on the battlefield. However, this peace wasn't going to last forever.
- All three strike teams were named after other planets in the solar system.
