The 3rd Battalion, 4th Marines, a.k.a. "the Thundering Third" was a regular marine force during the Guild Wars. It was led by Colonel Javier Vanderspool, who also commanded the elite 321st Colonial Rangers Battalion. Recruits for the batallion were trained at Turaxis Prime.
Many trainees who arrived on Turaxis II started under the Thundering Third, including Jim Raynor and Tychus Findlay. After their training, they would be reassigned to other units under Vanderspool, including the 321st Colonial Rangers Battalion.
During the Guild Wars, the 3rd Battalion was formed to conflict the Kel-Morian Combine on Turaxis II.It saw action early in the conflict, and took heavy casualties, but their leader, Colonel Javier Vanderspool, reported to UNN that those who survived had become veterans.
After their first few engagements, the Thundering Third were stationed at Fort Howe. It succeeded in repelling repelling a Kel-Morian attack, pushing the Kel-Morians out of Whitford and through the Snakeback Mountains.
