The tenth free expansion to City of Heroes, "Invasion," introduces a new group to the world of Paragon City and the Rogue Isles. Vanguard's primary role is to defend the world against alien invasion, no matter the cost. But not everyone agrees with their tactics or principles. Longbow has compiled a Top Secret report on Vanguard.

From the report:

"We have compiled a preliminary report on the Vanguard base located in the Paragon City neighborhood designated as the Rikti War Zone.

"Vanguard is an all-volunteer force funded by the United Nations Security Council. They have been in operation since the first Rikti invasion, and have maintained a philosophy of watchfulness and preparedness, always proclaiming that the next "alien threat" is lurking a day away.

"Although they have not been much in the news of late, we have observed considerable movements of troops and weaponry, and a higher-degree of battle-readiness in recent weeks than in past months. Their current command and operations center is located in the Rikti War Zone, and their primary North American agents are all stationed there."
