"On every world the Sith Empire strikes, we will be there too. We will sacrifice when necessary. We will never surrender. For hope; for freedom; for the Republic!"
Eventually, the squad fell under the command of Harron Tavus who led them during numerous engagements. This saw them face numerous skirmishes against the elite Shadow Fist unit of the Imperial Military.
A noted incident emerged when the squad was sent by General Garza to Ando Prime to cut off an Imperial offensive. The squad encountered more enemy soldiers than expected and were forced to call for extraction. But before Garza could get a rescue operation going, the Republic Senate shut it down. Garza had sent the squad to Ando Prime without the Senate's consent or knowledge, and the senators would not allow her to risk re-igniting war with the empire. The squad was left stranded in enemy territory, though they managed to return to the Republic. However, the incident left a dark scar on the team with many of its members believing that they were betrayed by the Galactic Republic. Thus, they planned to defect to the Sith Empire and were stationed on Ord Mantell when they were making their final preparations.
At the time, they were joined by a new recruit in the team who was unaware of Tavus's intentions. Eventually, the Squad initiated their plan though Tavus offered the new recruit to join them before they departed Ord Mantell and their service to the Republic. Afterwards, the recruit was made the new head of Havoc Squad and given the task of recruiting new members into the squad.
In the Cold War, the team was tasked with combating the Imperial threat and hunting down the renegade former members of the squad. At this time, the Special Forces unit was directed by GeneralGarza during their operations. In their travels, Havoc recruited defected Imperial Sergeant Elara Dorne and assault droid M1-4X into the squad, eventually tracking down all the traitors. Garza then promoted Havoc's CO to the rank of captain.
Havoc was soon called upon to extract an SIS agent on Tatooine, who had vital information on an Imperial superweapon codename Gauntlet, a powerful hyperspace cannon. While coordinating a joint military offensive, Garza required Havoc to be up to full strength with the needed specialists to destroy the Gauntlet. To that end, she dispatched Havoc Squad to recruit explosives expert Tanno Vik on Balmorra and technician Sergeant Yuun on Hoth, as well as extract the Safecrackers squad on Quesh. Participating in the assault, Havoc boarded and sabotaged the Gauntlet, completely vaporizing the superweapon. Upon returning to Coruscant, Garza commended Havoc's actions and promoted each member.
Unfortunately, their victory was not without consequences. Imperial GeneralRakton declared war against the Republic and captured the heads of state of many Republic-aligned worlds to allow Imperial forces to bypass their borders. Havoc stormed the station where the hostages were being held and freed them, earning Rakton's ire.
Garza soon dispatched Havoc to allocate forces from Belsavis, Voss and station A-77 to turn the tide of the war. Unfortunately, a paid Imperial agent, SenatorGrom Zian, under Rakton's orders, launched a sham inquiry into Havoc's activities to get the squad suspended. Luckily, the SIS had gathered evidence proving Zian's Imperial ties, allowing Havoc to return to the frontline. The squad soon faced off against Rakton on Corellia and defeated him. Havoc was then personally commended by Supreme ChancellorSaresh.
