It is always good to see a joint training exercise between US and Korean Soldiers:

U.S. Army 2nd Lt. Seong Kim proudly watched his Soldiers executing the Patriot missile reload drill.

Through well rehearsed hand signals and simple voice commands, the experienced U.S. crew proficiently removed one Patriot missile can off the launcher system and quickly replaced it with another utilizing their Guided Missile Transporter.

Seong Kim turned to his Republic of Korea counterpart 2nd Lt. Eugene Kim, smiled and said, “This is how we do it.”

The two platoon leaders from United States and Republic of Korea were part of an exchange program initiated by the 6th Battalion, 52nd Air Defense Artillery Regiment, 35th Air Defense Artillery Brigade to assist its Suwon Air Base sister unit, the Republic of Korea Air Force 553rd Patriot Fire Unit.

The program is usually conducted at battery level, focusing on the sharing of air defense tactics, techniques and procedures.  [USFK Website]
