Marc Pelini's leadership, 6-52 set the standard across all areas of readiness."Among the numerous accomplishments during Pelini's two-year command, the battalion completed Patriot missile System modernization while executing the relocation of Charlie Battery, 6-52 ADA Bn., from Osan Air Base to Camp Humphreys in order to enhance the battalion's readiness posture."It's absolutely astonishing how much we have asked Iron Horse Soldiers to shoulder, yet they continue to exceed the standards," Wright said.

"They achieved a level of proficiency unrivaled by any air defense unit. Whether it was maintaining or modernizing our major equipment, issuing parts, executing Table VIII and Table XII qualifications, or feeding our Soldiers; everyday, you did exactly what Command Sergeant Major and I asked of you."Lt. Col. Walker and his Family come to the Republic of Korea from Washington, D.C., where he served as Air and Missile Integrator in the Army G2 Staff."Words cannot express how honored and humbled I am to assume command of this historic and renowned battalion," Walker said. "Entrusted with fielding, training, employment and upgrading of systems, and achievement of gunnery certifications, Soldiers of the Iron Horse Battalion have performed superbly. The personal sacrifices of both the Soldiers and Family members is not something that can be quantified. I look forward to serving with you."
