The V Battalion stayed a secret organization for many decades. When the Thunderbolts came onto the scene the V Battalion were interested in the fact that there was a new Citizen V claiming to be the grandson of the original Citizen V that they were not previously aware of. The V Battalion used a mole named Miles Warton (aka Miles Warbeck) that they had placed in the New York City mayor's office. The NYC mayor had appointed Dallas Riordan to be the Thunderbolts liaison (the mayor wanted to be closely affiliated with the new superheroes after the supposed deaths of the Avengers and Fantastic Four). Miles's job was to monitor Dallas.
Eventually it was revealed that the Thunderbolts were actually the Masters of Evil and that the new Citizen V was none other than Helmut Zemo, the son of Heinrich Zemo, the man who had murdered the original Citizen V and most of the original V Battalion. Shortly after this V Battalion leader Roger Aubrey offered Dallas the mantle of Citizen V. Dallas was offered the role because her paternal grandfather was one of the early members of the reconstituted V Battalion and he gave his life in service of the V Battalion. Dallas began hunting the Thunderbolts using the cover story that she was the granddaughter of the original Citizen V (she was not). After a few adventures (including being framed as the second Crimson Cowl and imprisoned) Dallas left the V Battalion after she was ordered to assassinate Henry Peter Gyrich. The V Battalion tried to prevent Dallas from spilling their secrets to the Thunderbolts. Before Dallas could so she was teleported away by the Crimson Cowl but not before a skirmish between the V Battalion and the Thunderbolts ensued.
Dallas was left crippled and a captive in Latveria after her fight with the Crimson Cowl. Soon afterwards the actual grandson of the original Citizen V awoke from a 5 year coma in England. John Watkins III then became Citizen V. John went on to lead the Redeemers. Eventually it was discovered that Helmut Zemo, who was thought to be deceased after a battle with Scourge, had his mind downloaded into Watkins body as a result of a prank played by the Thunderbolt member Techno.
Helmut then began serving in the V Battalion, his enemies unaware of his true identity. Eventually Helmut was removed from John's body and John chose to remain as Citizen V. The Battalion would then go on to opposed Marduk, the Collective Man and Flag-Smasher, after which they lost their ship/base the Vanguard
Eventually Roger Aubrey chose to leave the V Battalion after a battle with the evil god Marduk. He appointed Jim Hammond the original Human Torch as his successor.
