The Liberation of Tirol was a major operation for the Pioneer Expedition.
History[]
After the Tirolian Empire had deflowered Optera, Zor had sent the last Protoculture Matrix off to keep it from the hands of the Robotech Masters and Invid. The Masters sent the Zentraedi who eventually found it oon Earth but were defeated and lost contact with Tirol. The Masters left their homeworld using what little Protoculture they had to make the journey while leaving the old and sick behind. The Invid Regent launched an attack against Tirol in an attempt to reclaim his peoples lost Flower of Life, but upon finding nothing, he left a subordinate in charge and returned to Optera.
Upon their arrival, the SDF-3 was attacked by the Invid forces at Tirol who succeeded in damaging the ships Space Fold Drive. As a result, the REF was stranded in Tirolspace and thus decided to make a push to liberate the Tirolian homeworld. After a battle with Invid forces, the SDF-3's Main Gun fired and wiped out many Invid. They learnt that Tiresia still remained, and as a result, Vice-Admiral Rick Hunter decided to send a ground force to liberate the capital. Led by Commander Vince Grant along with Colonel Jonathan Wolfe, this force consisted of the Fleet's Zentraedi complement and involved the use of the Ground Mobile Unit in what became known as Operation Groundhog.
Afterward, the Sentinels arrived and they teamed up to defeat the Invid Pursuer which had the power to destroy Tirol. After talks, Rick and Lisa alongside members of the REF went with the Sentinels to free the worlds occupied by the Invid, choosing to go to Karbarra]] next.
