Yeong-seon Seo, also known as the Four of Diamonds, is an artillery expert and officer in the Korean People's Army during Mercenaries: Playground of Destruction.

ExOps BioEdit

Name: Yeong-seon Seo
"Captain Seo is General Chang's light artillery expert, responsible for overseeing the manufacturing and deployment of RPG launchers, Surface to Air missiles, and tube-launched, optically-tracked, wire-guided missiles (TOWs). Seo is proficient in many types of armed and unarmed combat. He is considered highly dangerous."


The e-mail concerning Seo's location is sent by the CIA. Most of it was blacked out but the parts that aren't show that Captain Seo is west of Ichon. To find Seo, head to the three way intersection leading to Ichon, Seo is located on a small hill right here. At the top of the hill are road blocks and sandbags guarded by two KPA soldiers. There are 5 more soldiers in the area guarding Seo, who himself is armed with a RPG and a heavy machine gun is right next to him, making him very dangerous.

A Sungri Scout is parked nearby with a RPG soldier standing near it. At the back of the area near the edge of the hill, a MD-500 Scout is parked on a helipad with no pilot, it would be wise to quickly hijack it and use it to kill all soldiers in the area or to destroy it before any other soldiers get into it before you. The Player will have to be quick and careful to verify Seo alive as he can possibly kill them very quickly with his RPG.

He can be found in the Southern Province of North Korea, along with the Clubs, but the he and the other Diamonds can only be verified after the Ace of Clubs contract has been completed.

His exact location is between west of Ichon, north-east of Kaesong and south-east of Sariwon.


  • In the e-mail and the GSRN broadcast, Cho is referred to as a Lieutenant.
