Stec was one of the 100 Alpha Advanced Reconnaissance Commandos created from the unmodified genome of his clone template and bounty hunter Jango Fett . In addition to the flash training , in which all soldiers received a basic lesson on the development of their military abilities , Fett subjected Stec and the Advanced Reconnaissance Commandos to separate training into ideal special mission groups , capable of operating solely behind enemy lines due to their unique abilities . Because of their lack of obedience , the ARC generation after Jango Fett ' s departure from Kamino was transferred to Stasis and only reactivated two months after the beginning of the Clone Wars in the course of the Battle of Kamino . Stec was integrated as a sergeant in the command operations of the Republican military . Following the Battle of Muunilinst , ARC chief Fordo was given the task of carrying out an emergency rescue operation on the planet Hypori with his special mission command , the 10 of Muunilinst , and evacuating a group of Jedi , led by General Grievous , the commander - in - chief the droid army of the separatists , had been involved in a light sword fight .

In the approach of their LAAT / i gunship to the wreck of the " Acclamator " - class assault ship , where the Jedi were , the soldiers controlled their equipment for the upcoming deployment . When the cannonboat reached the inside of the destroyed team carrier , Stec and the rest of the Advanced Reconnaissance Commandos gathered behind Fordo . The two ARC soldiers with the heavy weapons left the ship last . While two of the soldiers were searching for the signs of life that Fordo had discovered in the ruins and structure , the ARC chief ordered the other clone warriors to run out . In the place where he had localized two other life signs , the soldiers reached the battlefield of the Light Sword battle between Grievous and the last surviving Jedi , Ki - Adi - Mundi . When Grievous tried to take a deadly blow against the Jedi Master , he noticed the approaching soldiers , who immediately opened fire on him . Stec went there for a small hill , which offered him a piece of ruins . Although Grievous was initially forced to flee further into the wreck in order to escape the ongoing shelling of the clones , he succeeded in breaking the formation of the soldiers with a surprising jump from the ceiling and killing four of them with their light bullets . Fordo then called the gunboat to help . While Grievous escaped from the fire of the repeating blocks and vehicle rockets , Fordo ordered the retreat to ensure the survival of the two rescued Jedi , Shaak Ti and Aayla Secura . In the process , Stec sat down at the edge of the passenger cabin in order to be able to cover Grievous ' s presumed abode after the start of the gunboat with the bombardment of his rotary blower .

When the soldiers reached the inner wall of the establishment , they were attacked by a Scorpenek Annihilatordroids . With his laser cannon he destroyed a wall of Durabeton , behind which the soldiers had sought cover , and destroyed within three minutes three of the four battle groups . The remaining soldiers , including Stec , withdrew from the factory . Afterwards , the ARC soldier told his superiors about the failed attempt on Colla IV . Although he did not know what kind of droids his clone brothers had fought and recommended that he not allow the colicoids to continue breeding on that planet . Gear .
